Why is my SetTeleportGui not working when teleporting between games?

Video: https://www.youtube.com/watch?v=FQ5zayujy1s&feature=youtu.be (The "Waiting for Players" screen is separate, not the screen we selected for :SetTeleportGui)

Hello all, I am using :ReserveServer, and when I teleport the player, :SetTeleportGui is not working. These are one player servers for the title screen, by the way.

Server Code (Game we are getting teleported from):

local TS = game:GetService("TeleportService")
local Players = game:GetService("Players")


game.ReplicatedStorage.Events.TeleportPlayer.OnServerEvent:Connect(function(player, code)
	
	game.ReplicatedStorage.Events.PrepareTeleport:FireClient(player)
	
	wait(2)
	
	local players = Players:GetPlayers()

	TS:TeleportToPrivateServer(5132212625, code, players)
	
end)

Client Code (Game we are getting teleported from):

local TS = game:GetService("TeleportService")



game.ReplicatedStorage.Events.PrepareTeleport.OnClientEvent:Connect(function()
	
	local clone = game.ReplicatedStorage.LoadingGUI
	clone.Parent = script.Parent
	local loadingScreen = game.ReplicatedStorage:WaitForChild("LoadingGUI")
	TS:SetTeleportGui(loadingScreen)	
	
	
end)

Client Code (Game we are getting teleported to) (Placed in ReplicatedStorage):

script.Parent:RemoveDefaultLoadingScreen()
local gui = game:GetService("TeleportService"):GetArrivingTeleportGui()
gui.Parent = game.Players.LocalPlayer.PlayerGui

These scripts give the result given in the video above. Any help is appreciated. Thanks!
