menu is showing 3 extra menu items

Why is showing 3 extra menu items. I can’t find how to remove them in settings. This is after I’ve created a clone of a site using Coursepress and imported into new site of Multisite network.

In other words: on one of my multisites when I imported all data, the menu is showing three extra menu items ‘Courses’ ‘Dashboard’ and ‘Logout’ how do I remove them?
