I understand what you mean, but between the base plate and cam cover, both don't perfectly align and snap into place. It partially sticks out; both parts are not machined to the point where they can mate perfectly. I never had this problem prior, but I have come across several of these units with other users, and they all exhibit the same thing.
@Arjun when the grub screw is closed is there much of a gap between the base plate and cam cover? From your pictures it looks like the grub screw is biting into the wrong place and I’d expect it to make a mark on the flat surface rather that the sloping edge - if you know what I mean
