ScreenGUI not visible after being cloned?

Hey! I am having trouble with my ScreenGUI not being visible after it is Cloned from ReplicatedStorage, I would like the GUI to be visible when the player is sitting down but for it to be deleted when the player stands up. Here is my code:

local Seat = game.Workspace.Nexus.Nexus:WaitForChild("Seat")

local player = game.Players.LocalPlayer

local gui = game.ReplicatedStorage.ScreenGui

local character = player.CharacterAdded:Wait()

local hum = character:WaitForChild("Humanoid")

hum.Seated:Connect(function(hit)
	print("Player detected on "..Seat.Parent.Name)
	local newGui = gui:Clone()
	newGui.Parent = game.StarterGui
	newGui.Frame.Active = true
	repeat wait() until not player.Character.Humanoid.Sit
	print("Player no longer detected on "..Seat.Parent.Name)
	wait(0.1)
	newGui:Destroy()
end)

And here is what happens:
