I have a datastore which count the deaths but it stopped working. Can someone help?

So I have three different leader stats folders in the player service: one for counting a players deaths, time spent in-game and their stage in the lobby but when I run my game it says that all three leader stats folders are not a member of the player. When I look at my player service in my character while in-game, there are three leader stats folders.

Deaths script:

local plrs = game.Players
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("Deaths") -- Change this with a different name. 

print ("Deaths leaderstats working")

plrs.PlayerAdded:Connect(function(plr)

    local jats = Instance.new("Folder") 
    jats.Name = "leaderstats"
    jats.Parent = plr

    local wipeouts = Instance.new("IntValue")   
    wipeouts.Name = "Deaths"
    wipeouts.Value = 0
    wipeouts.Parent = jats
    local Data = DataStore:GetAsync(plr.UserId)
    if Data then
        wipeouts.Value = Data
    end
    game.Players.PlayerRemoving:Connect(function(Player)
    DataStore:SetAsync(Player.UserId, Player.leaderstats.Death.Value) -- Change "Money" with your currency.
end)


    plr.CharacterAdded:Connect(function(char)

        local humanoid = char:FindFirstChild("Humanoid")

        humanoid.Died:Connect(function()

            wipeouts.Value = wipeouts.Value + 1

        end)        
    end)
end)

Time spent script =

local plrs = game.Players
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("Seconds") -- Change this with a different name.    

print ("Time leaderstats working")

plrs.PlayerAdded:Connect(function(plr)

    local jats =Instance.new("Folder")  
    jats.Name = "leaderstats"
    jats.Parent = plr

    local wipeouts = Instance.new("IntValue")   
    wipeouts.Name = "Seconds"
    wipeouts.Value = 0
    wipeouts.Parent = jats
    local Data = DataStore:GetAsync(plr.UserId)
    if Data then
        wipeouts.Value = Data
    end
    game.Players.PlayerRemoving:Connect(function(Player)
    DataStore:SetAsync(Player.UserId, Player.leaderstats.Seconds.Value) -- Change "Money" with your currency.
end)


    plr.CharacterAdded:Connect(function(char)
        while true do
            wait(2)
            wipeouts.Value = wipeouts.Value + 1
        end

        end)        
    end)

Stage script:

local dss = game:GetService("DataStoreService")
local obbyDS = dss:GetDataStore("ObbyData")

local checkpoints = workspace.Checkpoints
print("Checkpoint leaderstats working")


game.Players.PlayerAdded:Connect(function(plr)

    local obbyData = obbyDS:GetAsync(plr.UserId .. "-obbyStageProgress")

    local ls = Instance.new("Folder")
    ls.Name = "leaderstats"
    ls.Parent = plr

    local stage = Instance.new("StringValue")
    stage.Name = "Stage"
    stage.Value = obbyData or 1
    stage.Parent = ls

    local char = plr.Character or plr.CharacterAdded:Wait()

    char:WaitForChild("HumanoidRootPart").CFrame = checkpoints[stage.Value].CFrame

    char.Humanoid.Touched:Connect(function(touch)

        if touch.Parent == checkpoints then
            if (tonumber(touch.Name) and tonumber(touch.Name) > tonumber(stage.Value)) or touch.Name == "End" then
                stage.Value = touch.Name

                pcall(function()

                    obbyDS:SetAsync(plr.UserId .. "-obbyStageProgress", plr.leaderstats.Stage.Value)
                end)
            end
        end
    end)

    plr.CharacterAdded:Connect(function(char)

        local hrp = char:WaitForChild("HumanoidRootPart")       
        local humanoid = char:WaitForChild("Humanoid")

        hrp:GetPropertyChangedSignal("CFrame"):Wait()

        hrp.CFrame = checkpoints[stage.Value].CFrame

        humanoid.Touched:Connect(function(touch)

            if touch.Parent == checkpoints then
                if (tonumber(touch.Name) and tonumber(touch.Name) > tonumber(stage.Value)) or touch.Name == "End" then
                    stage.Value = touch.Name

                    pcall(function()

                    end)
                    game.Players.PlayerRemoving:Connect(function(player)
                                obbyDS:SetAsync(plr.UserId .. "-obbyStageProgress", plr.leaderstats.Stage.Value)

                    end)
                end
            end
        end)
    end)    
end)

This only started happening after I implemented a leaderboard for whoever has played the longest:

 local DataStoreService = game:GetService("DataStoreService")
local WinsLeaderboard = DataStoreService:GetOrderedDataStore("WinsLeaderBoard")

local function updateLeaderboard()
        local success, errorMessage = pcall (function()
                local Data =WinsLeaderboard:GetSortedAsync(false, 5)
                local WinsPage = Data:GetCurrentPage()
                for Rank, data in ipairs(WinsPage) do
                       local userName = game.Players:GetNameFromUserIdAsync(tonumber(data.key))
                       local Name = userName
                       local Seconds = data.value
                       local isOnLeaderboard = false
                       for i, v in pairs(game.Workspace.Leaderboardarea.Leaderboard.LeaderboardGUI.Holder:GetChildren()) do
                             if v.Name2.Text == Name then
                                  isOnLeaderboard = true
                                  break
                           end
                    end

                     if Seconds and isOnLeaderboard == false then
                            local newLbFrame = game.ReplicatedStorage:WaitForChild("LeaderboardFrame"):Clone()
                            newLbFrame.Name2.Text = Name
                            newLbFrame.TimeSpent.Text = Seconds
                            newLbFrame.Rank.Text = "#"..Rank
                            newLbFrame.Position = UDim2.new(0, 0, newLbFrame.Position.Y.Scale + (.08 * #game.Workspace.Leaderboardarea.Leaderboard.LeaderboardGUI.Holder:GetChildren()), 0)
                            newLbFrame.Parent = game.Workspace.Leaderboardarea.Leaderboard.LeaderboardGUI.Holder
                     end
              end
      end)

      if not success then
            print(errorMessage)
      end
end
local g =0
wait(30)
while true do

        for _, player in pairs(game.Players:GetPlayers()) do
              WinsLeaderboard:SetAsync(player.UserId, player.leaderstats.Seconds.Value)
        end

        for _, frame in pairs (game.Workspace.Leaderboardarea.Leaderboard.LeaderboardGUI.Holder:GetChildren()) do
              frame:Destroy()
            end

            updateLeaderboard()

    g = g+1
        print("Updated!",g)

        wait(60)
end
