How do I make the buttons work correctly?

Currently I'm having a problem where even though the quit button I made is made to bring the viewer back to the home screen, it goes to the copyright site instead. The quit buttons on the videos are on the same corner as the copyright button on the home screen. The buttons need to be on the same location so I can't move them so is there some overlapping going on or am I missing something?

Yes, overlapping buttons can cause both of them to be clicked. When you hide a layer (or overlay something), you should probably also set it to non-interactive (system > set layer interactive)
