Primary menu not visible after removing UberMenu

Site: added for admins only

I recently finished testing UberMenu and have deactivated and removed the plugin. Now the primary menu is no longer visible on Desktop or Tablet formats, but it is available on mobile devices. When I do a show source, I can see that the menu is always included in the page text. However, even at desktop widths I see:

<div id="mobile-menu" class="main-nav">

Is it normal that id=mobile-menu is always specified on the main nav wrapper?

I don't think I changed anything on my layout customization and have looked through the settings a few times. I've also flushed the browser cache and disabled the server side caching plugin. I even created a simple test menu, but it didn't show either.

Any ideas? And is this self-inflicted or something left over from the UberMenu test?

Thanks,
Don
