Ok the cable from the handle goes to the right hand catch that is mounted in the slam panel, and then there is a short cable from the right hand catch to the left hand catch. These are held into the slam in the slam panel by m6 torques bolts. The catches are handed and you have to remove both catches to fit a new link (left-to-right catch) cable. It sounds like you need a new cable and left catch. One other tip the new catches aren’t threaded to take the mounting bolts so tap them before you try and fit them.
