When installing Kwikset lock part of the shaft of the lock collides with the bolt

Question

The red box in the picture shows that the semicircular metal cutout on the bolt for the perpendicular shaft of the lock is in the way

I know this is not a manufacturing defect because the earlier Kwikset has the same colliding structure. So what am I misunderstanding here and how to install this part correctly?

Answer 1

The "cutout" where you're getting interference is a normal part of the latch mechanism. It needs to slide/retract slightly when you first assemble the pieces.

Here is a nice video demonstration:
