Menu Bar and Images Change according to device

idance.org
All of the menu bar options do not show all of the pages all of the time.
For example, on the pages podiums, coaches, contact, etc, I’ll only have 3 menu items. On my apply page, I’ll see all 9 menu items.
I created the menu under “appearance” and applied it under “customize”. I’d like to know how to make the entire menu show up on every page.

on the podium page, I’m getting a different set of images on mobile vs desktop. Now sure why this is happening either. If anyone could help out with this, it’d be much appreciated!

Hello there,

Did you use a menu plugin or something? By default the displayed items should be same across the site.
