Script save problem when a player joins a game?

So I was testing out my script and there was some type of a problem joining in the game where the script doesn't load up whenever a player joins a server until they reset for it to work. Although it works sometimes, it doesn't do it always.

game.Players.PlayerAdded:connect(function(player)
	local currentlevel = player:WaitForChild("leaderstats"):WaitForChild("Level")
	player.CharacterAdded:connect(function(char)
		if currentlevel.Value >= 2 then
			script.Parent.Parent.StarterGui.Stamina.Handler.Disabled = false
		end
		if currentlevel.Value >= 3 then
			script.Parent.Parent.StarterGui.DoubleJump.Disabled = false
		end
		if currentlevel.Value >= 4 then
			player.Backpack.ScriptStorage.PlayerMovement.ForwardDash.Disabled = false
		end
	char.Humanoid.Died:connect(function()
		if currentlevel.Value >= 2 then
			script.Parent.Parent.StarterGui.Stamina.Handler.Disabled = false
		end
		if currentlevel.Value >= 3 then
			script.Parent.Parent.StarterGui.DoubleJump.Disabled = false
		end
		if currentlevel.Value >= 4 then
			player.Backpack.ScriptStorage.PlayerMovement.ForwardDash.Disabled = false
		end
	end)
	end)
end)
