Trying to hide some menus

Part 1 of 3 if I may. I have two more membership questions but to keep things simple I will just start off with this one.

I set up Membership plugin and so far these are my issues...

I use Blogs-Mu Theme

The stranger level is activated and seem to be working for other areas of the site.

But is it it possible to hide these nav menus? (Activity - Members - Groups - Forums - Blogs) from visitors not logged in?

I set up a stranger level called visitor and dropped "BuddyPress Pages" in Negative Rules with those boxes checked but they still show.
