[Prototype]-Clickable button inside a hover menu in XD.

Hey! I created a Cart icon into my menu, and made it to expand on hover. When hovered, the Cart icon area expands and shows a Checkout button. This cart ison is a component on its own. Problem is that, when I copy the master component, the copies wont work!

No matter whether I copy it inside my main menu component OR just on its own. I've built the components now few times but can't get it work. Everything seems to be OK when reviewing the components in prototype mode.

Any ideas? Thanks in advance!
