I have one of my test labels on the board, turn into copper etched letters on the board. So it won't be silk screened like all the other label, it will be printed in copper.  I tried to delete it and can't, I tried to ungroup, it, unlock the whole board, nothing will get it off the board. The next I can do is make it a different label, and swap it.  Anyone ever see this happen?   Oh, and I also removed the copper poor, and put it back, I could not fix it in any way.
