ReplicatedFirst:RemoveDefaultLoadingScreen()未在Studio中触发

我又来遇到了另一个问题。我正在尝试为我的游戏制作自定义加载屏幕，但是RemoveDefaultLoadingScreen似乎未触发。有人能帮我吗？以下是我的代码：

local Players = game:GetService("Players")
local ReplicatedFirst = game:GetService("ReplicatedFirst")
ReplicatedFirst:RemoveDefaultLoadingScreen()
local TweenService = game:GetService("TweenService")
local Player = Players.LocalPlayer
local PlayerGui = Player:WaitForChild("PlayerGui")
PlayerGui:SetTopbarTransparency(1)
local Loading = ReplicatedFirst.Load
local ScreenGui = Instance.new("ScreenGui")
ScreenGui.IgnoreGuiInset=true
local Bar = Loading.Frame.TextLabel
ScreenGui.Name = "LoadScreen"
Loading.Parent = ScreenGui
ScreenGui.Parent = PlayerGui
local Info = TweenInfo.new(0.7,Enum.EasingStyle.Cubic,Enum.EasingDirection.InOut,0,true,0)
local Tween = TweenService:Create(Bar,Info,{Position=UDim2.new(0.8,0,0.6,0)})
spawn(function()
    while true do
        Tween:Play()
        Tween.Completed:Wait()
    end
end)
if not game:IsLoaded() then
    game.Loaded:Wait()
end
for i=0,1,0.1 do
    Loading.BackgroundTransparency=i
    Bar.TextTransparency=i
    Loading.Frame.Load.TextTransparency=i
    wait()
end
ScreenGui:Destroy()

除了第三行在Studio中不起作用之外，一切都正常运作。这是应该这样吗？非常感谢任何帮助。
