Only two of my leaderstats are saving?

I'm trying to save 4 leaderstats in a DataStore using Tables. For some reason, only the first two leaderstats(Energy and Credits) are saving. I also have a problem where when a player joins the game the Speed leaderstat is going straight to zero. There are no errors and i have tried it in Studio and the actual game, and still the same problem. Could anybody help?

Heres the code

local DSS = game:GetService("DataStoreService")
local AllDS = DSS:GetDataStore("AllDataStore")

game.Players.PlayerAdded:Connect(function(player)
    local stats = Instance.new("Folder")
    stats.Name = "leaderstats"
    stats.Parent = player

    local hidden = Instance.new("Folder")
    hidden.Name = "hidden"
    hidden.Parent = player

    local Energy = Instance.new("IntValue")
    Energy.Name = "Energy"
    Energy.Value = 1
    Energy.Parent = stats

    local Credits = Instance.new("IntValue")
    Credits.Name = "Credits"
    Credits.Value = 1
    Credits.Parent = stats

    local Speed = Instance.new("IntValue")
    Speed.Name = "Speed"
    Speed.Parent = stats
    Speed.Value = 8

    local Jump = Instance.new("IntValue")
    Jump.Name = "Jump"
    Jump.Value = 70
    Jump.Parent = hidden


    local playerUserId = "Player_"..player.UserId


    local data
    local success, errormessage = pcall(function()
        data = AllDS:GetAsync(playerUserId)
    end)


    if success then
        Energy.Value = data.Energy
        Credits.Value = data.Credit
        Speed.Value = data.Speed
        Jump.Value = data.Jump
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    local playerUserId = "Player_"..player.UserId

    local data = {
        Energy = player.leaderstats.Energy.Value;
        Credits = player.leaderstats.Credits.Value;
        Speed = player.leaderstats.Speed.Value;
        Jump = player.hidden.Jump.Value;
    }

    local success, error,essage = pcall(function()
        AllDS:SetAsync(playerUserId, data)
    end)

    if success then
        print("Data was saved")
    else
        print("Did not save")
        warn(errormessage)
    end


end)
