I'm not sure what you are asking.
Can you see the broken off piece?
If you don't use that row, everything will probably be fine.
My breadboards are made with the clips in separated little 'ditches', so something in one won't move around to the others.
They have a thick 'tar-like' backing, so if yours are the same, it is hard to peel off without damaging it.
