[Plugin: Author Avatars List] Link to profile not working

I installed the plugin (on a WPMU Site) and set it to the List of Commentators with link to their BP profile. For example when I set the number on 10 people only one of them gets a link to his profile, the other avatars show only the name (when activated), not the link!
