[Help] Inventory Action Menu Won't Detect Clicks

My problem is this: I have a working inventory system that properly displays the items and the OnClicked event for each slot works. When it’s clicked, I want an action menu to appear that has buttons such as Use, Split Stack, Drop and Cancel. Currently, when a slot is clicked it displays the menu and updates it, so if the item cannot be used it doesn’t have the use button and so on. But whenever I try and click these buttons it doesn’t detect it. I’ve set the disabled colour to bright red and the buttons aren’t disabled. They don’t change appearance on hover either; I don’t understand what the problem is, and I can’t find a solution.

Any help will be appreciated, thanks in advance.
