DataStore Not Saving/Loading how to fix?

My DataStore script won't save or maybe won't load players data. I have a button in game that raises the values of GoldRubyC and CollectionValue

local datastore = game:GetService("DataStoreService"):GetDataStore("tablohazerjia1")


game.Players.PlayerAdded:connect(function(player)
		local PlayerProfile = Instance.new("Folder")
	PlayerProfile.Name = "PlayerProfile"
	PlayerProfile.Parent = player
	
	
	-------------------- [Collected Treasure Verified]-
	local TreasuresCollected = Instance.new("IntValue")
	TreasuresCollected.Name = "TreasuresCollected"
	TreasuresCollected.Parent = PlayerProfile
	---------------------------------------------------
	
	
	---------------------[Treasures]--------------------
	local GoldRubyC = Instance.new("IntValue")
	GoldRubyC.Name = "GoldRubyC"
	GoldRubyC.Parent = PlayerProfile.TreasuresCollected
	---------------------------------------------------
	
	
	---------------------[Collection Value]------------
	local CollectionValue = Instance.new("IntValue")
	CollectionValue.Name = "CollectionValue"
	CollectionValue.Parent = PlayerProfile
	--------------------------------------------------

	
	
	local key = "user_" .. player.userId
	
	local storeditems = datastore:GetAsync(key)
	
	if storeditems then
		TreasuresCollected.Value = storeditems[1]
		GoldRubyC.Value = storeditems[2]
		CollectionValue.Value = storeditems[3]
	else
		local items = {TreasuresCollected.Value, GoldRubyC.Value, CollectionValue.Value}
		datastore:SetAsync(key, items)
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	local items = {player.PlayerProfile.TreasuresCollected.Value, player.PlayerProfile.TreasuresCollected.GoldRubyC.Value, player.PlayerProfile.CollectionValue.Value}
	local key = "user_" ..player.userId
	
	datastore:SetAsync(key, items)
end)
