So the lower spots of the design show the raised areas where the first ear was placed. The second hub process removed the higher areas of the die, but the lower devices didn't get erased as there were no design affects on that area, so the first hub process was erased, except for the arrows are showing. This is similar to the doubled eye lids. The first/second hub processes left marks that would not be erased on the next hub process. It is the die that is affected, it is not a striking issue. Hope this helps.
