Designer only shows all pages in Mobile but I can only see/edit the home page shows in desktop/tablet view

In designer, the canvas shows all the template pages in Mobile (L) and Mobile (P) but only the home page shows in desktop/tablet view. Everything is “visible” in element settings and if I change the only 2 hidden components to “none” (the one is for the menu options which then opens up and the other makes everything orange - whether I changed it to ‘block’ or ‘flex’).

The only difference I can see is that the “nav_menu_component” is hidden on Mobile views, but changing this does not solve the problem.

How do I get these pages to show on desktop so i can edit them?
