I am having some drawings in my drawing manager come up as uneditable. They were created erroneously and I need to get rid of them to clean up the document so that I can begin putting my sheets together. I have attached two pictures. When I try to delete them they tell me that they are locked or shared by a team member. This project has no team members so that can be the problem, and I have unlocked everything I know to unlock. Thanks for your help.
