Hop into your DB via phpMyAdmin and see if there is one hidden per chance in the Active Fields. It may have gotten misnamed and is not showing up for you. We had a problem like this just the other day on D6 site where the Membership field (block 43) got renamed to Membership Levels and while you think it would show up fine, no matter what we did would get it to reappear until we corrected the name in the DB using the edit function.
I am check intro my DB via phpmyadmin often and see nothing problem with database.. no hidden active Fields ... this issue can't fixed on Dolphin7?
