WPMU Dev Avatar issue in CoursePress Pro

I am using Avatars and the avatars for Instructors in CoursePress Pro are not filling the entire box. It does work properly when a Gravatar is used.

Can this be fixed or are the avatars from your Avatar plugin not compatible with CoursePress Pro?

Thanks,
Jesse
