Why is data not saving even though it prints that it got saved...?

I have a script that saves data of a folder full of intvalues, when i enter the game and the values change, i leave and rejoin and no data have been saved to how i had it before i left. is it a script problem or a ingame problem? help

script:

there are not any errors in the output

local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local SaveDataStore = DataStoreService:GetDataStore("SaveData6")

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local nametagPurchases = ReplicatedStorage:WaitForChild("NametagPurchases")
local firstPage = nametagPurchases.FirstPage


local function SavePlayerData(player)

	local success,errormsg = pcall(function()

		local SaveData = {}

		for i,stats in pairs(firstPage:GetChildren()) do
			
			if stats:IsA("IntValue") then
												
				SaveData[stats.Name] = stats.Value				
				
			end			
		end	
		print("saving player data...")
		SaveDataStore:SetAsync(player.UserId,SaveData)
	end)

	if not success then 
		return errormsg
	end   
end 


Players.PlayerAdded:Connect(function(player)

	local Stats = Instance.new("Folder")
	Stats.Name = "leaderstats"
	Stats.Parent = player
	
	local points = Instance.new("IntValue",Stats)
	points.Name = "Points"

	local Data = SaveDataStore:GetAsync(player.UserId)

	if Data then

		for i,stats in pairs(firstPage:GetChildren()) do
			
			if stats:IsA("IntValue") then
														
					stats.Value = Data[stats.Name]					
													
			end
		end  
		
	else
		
		print(player.Name .. " has no data.")
		
	end 
end)


Players.PlayerRemoving:Connect(function(player)

	local errormsg = SavePlayerData(player)

	if errormsg then 
		warn(errormsg)  
	end 
end)

game:BindToClose(function()
	for i,player in pairs(Players:GetPlayers()) do 

		local errormsg = SavePlayerData(player)
		if errormsg then
			warn(errormsg)
		end   
	end
	wait(2)
