menu links added as default in secondary menu

I installed CoursePress and after a few small fixes it seams to work very well!

Im running it with the plugin only and wit BuddyPress as well. When installing the plugin it ads three menu links to my secondary menu as default, how do I remove theses? I’v tried with CSS but I cant seem to be able to remove them.

If needed see here:

Looking forward to hear from you.
