Just the knobs? This implies old locks with the long inset lock. Are they too tight and not allowing the catch to fully come out? If newer stile locks and you changed the entire lock, then there is some very small difference in the plunger and the strike plate between manufactures. Using the strike plate supplied with the lock should fix the problem or it may need to be adjusted just a bit.
The door latch may not be springing back into place due to a worn-out or broken spring within the latch mechanism. This can prevent the latch from returning to its original position after being released.

"My lock is stuck"?
AnswerIt is on the back side of the door latch assembly inside of the door.
Inside the door, on the back of the door latch/lock assembly.
Often the latch has been closed and the door won't catch until the latch is popped back. Use a screwdriver or other tool, make sure the door is unlocked then operate the inside door handle and open the latch lever with the screwdriver.
To adjust the length of a door latch, you can typically use a screwdriver to loosen the screws on the latch plate and then adjust the position of the latch to make it longer or shorter. Once you have made the adjustment, tighten the screws back in place to secure the latch in its new position.
The door may not latch properly due to misalignment of the latch and strike plate, a loose or damaged latch mechanism, or a warped door.
Usually if you loosen the screws on the latch receiver mounted on the cab edge, the latch can be shifted up/down or front/back.
A door latch shim can be used to adjust the alignment of a door latch by placing it behind the latch plate. This helps to ensure that the latch engages properly with the strike plate, allowing the door to close and lock smoothly.
Replace the door latch.
To properly install a door handle latch, first ensure the latch is the correct size for the door. Next, mark the placement of the latch on the door edge and use a chisel to create a recess for the latch plate. Attach the latch mechanism to the door and secure it with screws. Test the latch to ensure it functions properly before installing the door handle.
