I can't delete deactivated popups from the list

Creating test pop ups, so I have a few extra I don't need once I get my approvals. I deactivate them, select the checkbox and try to apply "Move To Trash" but get this error - "You are not allowed to move this item to the Trash."

Not a big deal yet, because we haven't created that many. But it will get quite messy as we move forward if this isn't resolved.

Yes, I am the admin.

Thanx for any help.
