Perhaps it is the lock itself. See attached photos please. can you identify the lock part #? The screws are 3.75" o.c. and the lock itself is 3.25" tall.
to give you some context, i add two photos of the door pull, and two photos of the door frame with pull removed.
the issue is best described as follows: there is no tension in the lever that is part of the pull assembly, and so it does not function as intended.
