I have a simple surface with slope labels that will not delete. They move and grip edit just fine, they just won't go away! I searched the forums a bit and didn't find any others with this situation. Work around: set the label style visibility to false and use a copy of the style with final desired labels to finish the job.
Audit doesn't find any errors, an open and close doesn't solve it either.
Have you heard of this? Can it be fixed?
