BuddyPress.org

This is a great and useful plugin. We’re planning on using it to do a content centered around who invites the most people to the site. One problem I’m having is that rank is only showing on some profile and not others. Any idea of why this would be?
Examples:
Not showing on this profile
http://supportforspecialneeds.com/members/bedwards3447/

Showing on this profile
http://supportforspecialneeds.com/members/siobhanwolf/

(At least that’s how it was at the time I posted this — maybe it’ll spontaneously resolve? Stranger things have happened!)
