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)
