GUI won't show up after being exited only once?

I have a click detector that opens up two GUIs when clicked, and it only works once. I can open up the GUI, interact with it, and close it. It works fine until i try to open it again. Instead of opening, it does nothing. There are no errors.

All scripts that interact with the GUIs:

Click Detector:

local Players = game:GetService("Players")


script.Parent.ClickDetector.MouseClick:Connect(function(player)
	player.PlayerGui.BuyLighter.Enabled = true
	player.PlayerGui.BuyWeapons.Enabled = true
end)

Exit Button in GUI

script.Parent.MouseButton1Click:Connect(function()
	script.Parent.Parent.Enabled = false
	script.Parent.Parent.Parent.Buy.Enabled = false
end)
