(Solved)Why do not save the values of level and experience in the DataStoreService?

Hello, I have several script 2 in ServerServiceScript and one in the player all are server script, where the player's position is saved, that works perfectly, then I have the level and experience that work if the player dies or is reset, but when I leave the game either in stop or in the menu button leave, the experience and level data are erased, from the same roblox application, but if the position is saved perfectly. What can be?

--script Menu in ServerServiceScript

local Players = game:GetService("Players")
local MenuEventSave = game.ReplicatedStorage:WaitForChild('MenuEventSave')
local MenuEventReset = game.ReplicatedStorage:WaitForChild('MenuEventReset')
local DataStoreService = game:GetService("DataStoreService")
local DataPosition = DataStoreService:GetDataStore("PlayerPosition")
local DataLevel = DataStoreService:GetDataStore("PlayerLevel")
local DataExp = DataStoreService:GetDataStore("PlayerExp")
local lastPosition
local tableToVector = {43.809, 112.453, 103.157}
MenuEventSave.OnServerEvent:Connect(function()
	for i, playerChild in pairs(Players:GetChildren()) do
		for i, player in pairs(Players:GetPlayers()) do
			lastPosition = player.Character.HumanoidRootPart.Position
			if lastPosition then
				DataPosition:SetAsync("Player_" .. player.UserId, {lastPosition.X,lastPosition.Y,lastPosition.Z})
				DataLevel:SetAsync("Player_" .. player.UserId, player.leaderstats.Level.Value)
				DataExp:SetAsync("Player_" .. player.UserId, player.leaderstats.EXP.Value)
				print("Set1")
			end
		end
	end
end)
MenuEventReset.OnServerEvent:Connect(function()
	for i, playerChild in pairs(Players:GetChildren()) do
		for i, player in pairs(Players:GetPlayers()) do
			lastPosition = player.Character.HumanoidRootPart.Position
			if lastPosition then
				DataPosition:SetAsync("Player_" .. player.UserId, tableToVector)
				DataLevel:SetAsync("Player_" .. player.UserId, 0)
				DataExp:SetAsync("Player_" .. player.UserId, 0)
				print("Set2")
			end
		end
	end
end)
