Gitto, we may be at cross purposes here. I don't dispute there's an unclued entry however many times you repeat the instruction; my point is that once you have completed the instruction once, you have filled the empty space left by the unclued entry with the first title. So when you start again, the only way to get the empty space back is to erase what you've filled in, which to me isn't the same as leaving it empty (unless you start again with a blank grid). I do agree with you that entering the second answer is the only way to complete the instructions for the second time, with the reservations you and others have expressed about removing the more comprehensive first title.
