Leaderstats not showing when I test my game?

This doesn't usually happen, but my leaderstats for my new game isn't showing. Here is the script. I added it to ServerScriptService.

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("MoneyStats")

game.Players.PlayerAdded:Connect(function(Player)
	local Leaderstats = Instance.new("Folder", Player)
	Leaderstats.Name = "leaderstats"
	
	local Gold = Instance.new("IntValue", Leaderstats)
	Gold.Name = "Gold"
	Gold.Value = 0
	local Diamonds = Instance.new("IntValue", Leaderstats)
	Diamonds.Name = "Diamonds"
	Diamonds.Value = 0
	
	local Data = DataStore:GetAsync(Player.UserId)
	if Data then
		Gold.Value = Data.Gold
		Diamonds.Value = Data.Diamonds
	end
end)

game.Players.PlayerRemoving:Connect(function(Player)
	DataStore:SetAsync(Player.UserId, {
		["Gold"] = Player.leaderstats.Gold.Value;
		["Diamonds"] = Player.leaderstats.Diamonds.Value;
	})
end)

That should've worked just fine but I also recommend using an or statement rather than setting the value twice. That way, if it can't retrieve the player's data, it sets is to 0. You can do that like this:

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("MoneyStats")

game.Players.PlayerAdded:Connect(function(Player)
    local Leaderstats = Instance.new("Folder", Player)
    Leaderstats.Name = "leaderstats"

    local Gold = Instance.new("IntValue", Leaderstats)
    Gold.Name = "Gold"
    local Diamonds = Instance.new("IntValue", Leaderstats)
    Diamonds.Name = "Diamonds"
    pcall(function()
	 locall Data = DataStore:GetAsync(Player.UserId)
	 Gold.Value = Data.Gold or 0
	 Diamonds.Value = Data.Diamonds or 0
   end)
   
end)

game.Players.PlayerRemoving:Connect(function(Player)
    DataStore:SetAsync(Player.UserId, {
        ["Gold"] = Player.leaderstats.Gold.Value;
        ["Diamonds"] = Player.leaderstats.Diamonds.Value;
    })
end)

Also make sure API Services are enabled
