Yep, that sounds normal alright. It happens to me too, so I guess you just put the group bio in your bio and say "read [YOURCHARACTERNAME]'s bio for details", and if not, I guess just make a character and let them join the group and name them "The Group Bio" or something. Then put the actual group bio in there and stuff. :/ Sadly this thing cannot be fixed with the group bio thing as I recall.
I only gave some suggestions to help your situation, really. Hope this helped somewhat.
