That’s great that it’s displaying better for you. Could you do one of two things regarding the menu?
1.) Show me a screenshot of what you see and circle the problem so it stands out better for me. And a second screenshot of another page where it is not a problem, circled with what you expect it to look like when working.
2.) Email me a copy of your theme (firstname.lastname@example.org) so I can check it out, and include a link to this thread ( https://www.wcvendors.com/help/topic/menu-hidden-by-vendor-and-pro-dashboard/ ) so I know what thread the theme is meant to help diagnose. 🙂
