Nut between handle and body isn’t the same on the both sides

I recently noticed my OB-4’s handle isn’t symmetrical, the left side’s connector between handle and body have no gap.

But the right side connector (between body and handle) has a gap, the nut that can be screwed tighter, but when it screwed tighter and leaves no gap, then the handle can only turning half way up, look inside it have a fixed edge on the top angle and it will align with the edge on the nut when the handle perfectly vertical. As image shows:

Is this normal? It isn’t symmetrical tho. I didn’t notice that 3 years. Now it looks weird.

Is your OB-4 same?
