I used the flood tool(?) to select an area of a drawing I scanned and then pasted in. Now it seems it gets attached to everything else I paste in and I can't find it to remove or delete it. I know I'm not describing this well but I have lost my mind. The selection area can be moved and can be resized but it appears to be attached to anything that gets pasted now and nothing that gets pasted can be moved or resized. I've attached a photo where you can see that the selection has nodes(?) but there's a blue box around thing I've pasted and no nodes(?). How do I remove this so I can start pasting things in again?
