I have a snapshot that I saved in my toolbox. The picture went away and the tool was grayed out, so I deleted it. The empty snapshot got onto my document while I was doing this process. I did not realize it at the time and continued marking up the document. Everything else is working properly. Now I have the grayed out rectangle on top of an equipment schedule and it was the second thing I did so I cannot undo it without losing an hours worth of work. It is blocking me from editing a mark-up underneath it. When I right click lock is chosen but it will not unclick. I went to the mark ups dialogue at the bottom of the screen and tried to delete or unlock it from there. It refuses to unlock or delete. Nothing else - other mark-ups - are locked.
How can I get rid of it, so I can edit the mark-ups underneath it? Can I undo just this object without having to undo everything?
