I have one of these privacy locks fitted to my bathroom door:

A curious problem has started happening with the lock, when you turn the door handle (oval knob) clockwise to open the door, the latch doesn't retract fully into the lock unit. Instead, it retracts at a bit of an angle, where the top of the latch is fully retracted, but the bottom sticks out a bit. This causes the door to stick...if you give it a shove, it'll usually open.
However, if you turn the oval knob counter-clockwise, the latch retracts fully, and the door opens with no issue at all.
I have two more of these privacy locks on other doors in the house, and they're working ok. So I replaced the internal lock unit with a spare I had left over from the reno, thinking this would fix it. but the same problem is happening. So I guess it must be related to one of the other parts of the lock set. Any thoughts?
