Table custom view problem after widget delete

Hi!

I added several widgets to a custom table view. I made some mistakes, so I deleted some of them. The problem is, that every time I enter to editor mode, the previously deleted items come back again. They come back even if log out and back. If I don't log out or switch to editor mode they do not appear. 

The one after deleting:

After entering the editor mode again:

Is it some kind of bug, or it is a problem in my database? I use V3.09 in SQ mode, with win7
