BB Bold :: Cannot Save A Group In OS7 On BB9930

I updated from 9650 to 9930. I had a group in my contacts which migrated to the new phone. I needed to add a new contact, and then add them to this group. The contact creation works fine, but when I try to add the new contact to the group on the 9930 (OS7), I cannot save the group with this change. I select "save", but nothing seems to happen. I continue to get a dialog box with "Save/Discard/Cancel" options, but the phone only responds to cancel or discard.So then I tried to create a new group on my 9930. I was able to add one contact to it and save, but when I tried to add a second, I simply cannot save the group with this change. I rebooted the phone and tried again, to no avail.
