saving the bool instance and it's value?

Hello guys I'm new to script and I'm facing an error. I made a script that saves the bool values from the player's folder (which is called "ownership"). Now my problem is that sometimes when I rejoin it saves the previous bool values that the new ones. For instance, I have 3 bool values, first called "first", second called "second" and third called "third".

1st play test: I set the first = true, second = false, third = false (when the player leaves; the script saves these values and when he rejoins he will have these values)

2st play test: I set the first = false, second = true, third = false

3st play test: I joined the game and have the values that correspond to the 1st play test

if you have any idea please let me know. The error occurs randomly

here is the script:

local titlefolder = game:GetService("ReplicatedStorage"):FindFirstChild("Titles") -- the folder that contains the values

local datastore = game:GetService("DataStoreService")

local savedata = datastore:GetDataStore("SaveTitles")


game.Players.PlayerAdded:Connect(function(plr)
    wait(.5)

    local data

    local ownership = plr:WaitForChild("ownership") -- the values that the player has

    local success,errormessage = pcall(function()
        data = savedata:GetAsync(plr.UserId)
    end)

    if data ~= nil then
        if success then
            for i,v in pairs (data) do
                if ownership:FindFirstChild(i) == nil and titlefolder:FindFirstChild(i) then
                    local clone = titlefolder:FindFirstChild(i):Clone()
                    clone.Parent = ownership
                    clone.Value = v
                end
            end
        end
    end
end)

game:BindToClose(function()
    for i, plr in pairs(game.Players:GetPlayers()) do
        plr:Kick() -- Apparently so that it fires the PlayerRemoving function?
    end
end)

game.Players.PlayerRemoving:Connect(function(plr)
    wait(1)
    local itemsowned = {}
    local ownership = plr:WaitForChild("ownership")

    for i,v in pairs (ownership:GetChildren()) do -- from the player's folder
        itemsowned[v.Name] = v.Value -- (im making a dictionary)
    end

    for i,v in pairs (itemsowned) do
        print(i.." = "..tostring(v))
    end
    local success,errormessage = pcall(function()
        savedata:SetAsync(plr.UserId, itemsowned)
    end)

    if success then
        print("Titles successfully saved")
    else
        warn(errormessage)
    end
end)
