I am trying to edit the group on a collection and am running into issues. The collection is 7bbfdc65-2b7c-446f-b415-3fd3362b6f3b. It currently belongs to the groups "Bighorn Basin P-E Boundary" and "P-E fossils". I am trying to remove the group "P-E fossils". When I hit submit (after search PBDB of course!), I am returned to the blank collections form to enter a new collection, and no edit is made.
