My datastore script is working and it output [Player left, saved DATA],
but when i rejoin the game the data is not saved.

my API services is enabled, and its not in studio.
Data script:

local DataStore2 = require(game.ServerScriptService.DataStore2)
DataStore2.Combine("DATA", "Clicks", "Diamonds", "Rebirths")


game.Players.PlayerAdded:Connect(function(player)
	local clicksDataStore = DataStore2("Clicks", player)
	local diamondsDataStore = DataStore2("Diamonds", player)
	local rebirthsDataStore = DataStore2("Rebirths", player)
	
	
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local clicks = Instance.new("IntValue")
	clicks.Name = "Clicks"
	clicks.Parent = leaderstats

	local diamonds = Instance.new("IntValue")
	diamonds.Name = "Diamonds" 
	diamonds.Parent = leaderstats

	local rebirths = Instance.new("IntValue")
	rebirths.Name = "Rebirths"
	rebirths.Parent = leaderstats
	
	
	if clicksDataStore:Get() ~= nil then
		clicks.Value = clicksDataStore:Get()
	else
		clicks.Value = 0
	end
	if diamondsDataStore:Get() ~= nil then
		diamonds.Value = diamondsDataStore:Get()
	else
		diamonds.Value = 100
	end
	if rebirthsDataStore:Get() ~= nil then
		rebirths.Value = rebirthsDataStore:Get()
	else
		rebirths.Value = 0
	end
	
	
	clicks.Changed:Connect(function(player)
		clicksDataStore:Set(clicks.Value)
	end)
	diamonds.Changed:Connect(function(player)
		diamondsDataStore:Set(diamonds.Value)
	end)
	rebirths.Changed:Connect(function(player)
		rebirthsDataStore:Set(rebirths.Value)
	end)
end)
