Getting control of the Edu Clean navigation menu

I'm trying out some WMPU DEV themes to refresh my site and to get better compatibility with some of the plugins you offer.

In testing out the Edu Clean theme, on activation, I found that my navigation bar is all messed up.

The screenshot here is what I get.

Edu Clean doesn't seem compatible with the WP ver 3 menus system and I would to have better control of it because I don't necessarily need to have all my BP links in there, and certainly not all my pages.

Can someone tell me more about how to control this?
