I think this is resolved now. What it looks like happened was the Group/Audience was renamed (or changed from checkboxes to dropdowns). That changes the ID number that the Audience/Group uses but Gravity Forms still had the old one. Specifically the '0dbb8003d0' below is the "old" one and was present in the error message.
