The display of wikis from the Widget for WordPress Wiki seems to be having problems. If more than one parent has wikis assigned to them, all of the parents do not display. For the one wiki parent that does display, not all of the wikis assigned to that parent display. If all of the wikis are parents (with no assigned wikis), all display correctly.
Using WordPress Wiki 1.0.0, WordPress 3.1, and BuddyPress 1.2.8.
