I am working on a file that has 2 pages and 2 menus which are linked to the pages but when i click on the menu button(s) during my prototype presentation, the link opens the design file and not the prototype page. I am copying the link to the page and adding the interaction. My menus are part of a published library with components of menus and UI elements 

I have tried to swap out the page link and replace it with a link to a specific frame and still getting the same issue. 

This seems to happen only with page links, overlays etc work correctly. i notice the URLs for the page or frame links has a figma.com/design and the prototypes have a /proto url structure, is this some sharing settings issue that I am not able to copy the right /proto links ? 

I think i am missing something obvious here :(
