Group Icon Bug

Hi. I am trying to stylize the display of groups on my Blogs MU buddy press blog (see: biotechstart.org). You can see the icons here. I have two issues I'm trying to resolve:

1) Only 2 of my groups appear in the list (I currently have 3 groups total). See: http://www.biotechstart.org/groups

2) I would like the groups to have their names in text underneath. How do I allow for this?

Thanks,
-James
