Why doesn't this billboardgui textbutton not show up when I walk to the part?

I have a placement system, and I have it so that when you equip a tool, and click it will clone the structure into workspace and create a billboardgui with a textbutton inside of a screengui inside of startergui. The problem is, I tested it and the TextButton doesn't show up. Here is the script:

game.ReplicatedStorage.RemoteEvents.PlaceStructure.OnServerEvent:Connect(function(Player,Structure,PrimaryCFrame)
	if Structure == "Workbench" then
		local Clone = game.ReplicatedStorage.Structures[Structure]:Clone()
		Clone.Parent = game.Workspace
		Clone:SetPrimaryPartCFrame(PrimaryCFrame)
		local BillBoardGui = Instance.new("BillboardGui")
		local TextButton = Instance.new("TextButton",BillBoardGui)
		local ScreenGui = Instance.new("ScreenGui",game.StarterGui)
		BillBoardGui.Parent = ScreenGui
		BillBoardGui.Adornee = Clone.Center
		BillBoardGui.AlwaysOnTop = true
		BillBoardGui.MaxDistance = 17
		TextButton.BackgroundColor3 = Color3.fromRGB(85,170,255)
		TextButton.BorderSizePixel = 0
		TextButton.Size = UDim2.new(0,50,0,50)
		TextButton.Position = UDim2.new(0,70,0,0)
		TextButton.Visible = true
		TextButton.MouseLeave:Connect(function()
			TextButton.BackgroundColor3 = Color3.fromRGB(85, 170, 255)
		end)
		TextButton.MouseEnter:Connect(function()
			Clone.Top.Hover:Play()
			TextButton.BackgroundColor3 = Color3.fromRGB(54, 108, 162)
		end)
		TextButton.MouseButton1Click:Connect(function()
			Clone.Top.Click:Play()
		end)
	else
		local Clone = game.ReplicatedStorage.Structures[Structure]:Clone()
		Clone.Parent = game.Workspace
		Clone:SetPrimaryPartCFrame(PrimaryCFrame)
	end
end)
