And you think I need to lap the yellow 8000 stone some more?

Yea, and you will need to chamfer or round the corner so the chamfer or rounding is past the chip on the face of the stone. So that when you hone on the face, you do not feel the chip, Better to have a ¼ inch bevel, than loose a ¼ inch of thickness.

Or, better yet, why not just use the good side?

If you are going to use the same stones for knives, use one side for razors and the other side for knives. Just mark the side of the stone, so you know which side is which.
