A couple of questions need to be asked.
1. Does the lock function normally when removed from the gun?
2. With the lock removed, do the triggers work as expected?
3. Has the trigger plate moved further into the trigger inlet?
If the lock works when removed from the gun, the problem is with the triggers.
In most cases like this my first look is at the trigger. Sometimes the stock expands or contracts or the trigger plate is over tightened when reinstalled and the plate is now deeper in the trigger plate mortise.
First step at a fix is to make a shim for the trigger plate. This will lower the trip lever so it is not pushing the sear out of the full cock notch.
Remember, do not over tighten the lock plate screws or the screws holding the trigger plate in the stock.
I hope you have a simple fix.

Okay, lets take a look at the lock. Specifically we are going to look at the tumbler and the nose of the sear. What does the engagement of the sear nose and the full cock notch look like.
The nose of the sear should be sharp and fit perfectly in the notch in the tumbler. If the sear is sharp, the notch needs to be full across the tumbler with no chips out of the edge. Perhaps the tumbler is not properly hardened and the notch is too worn to fully function. Repair of the tumbler to cut a new notch and reshape the full cock notch is the job for a black powder gunsmith. You can get a new tumbler and sear from traditions. the parts will likely have to be polished to fit perfectly and hardened to ensure that the lock functions for a long time.
