Detail view selection halo

We have 2024 version at work and now have a problem when inserting a Detail View. The circle used to select a detail remains and I cannot find a way to hide or delete it. Not the detail view you create (I can easily get rid of that); the subject detail.  Everything I google shows how to get rid of halo around newly created detail view, I'm looking for the subject (or selection) halo. Any help is greatly appreciated.
