Do you have a retireing cam on the unit. I thought I had a lock issue with the one i was working on but it ended up being the cam hitting the lock in flight which dropped the cam and now it is out of the dz with the locks open and wouldn't relevel unless i jumped out the locks at the controller. I too couldn't just jump out 1 lock at a time. I ended up adding a little to the dz mag so if that situation ever happened again it would see dz and level back into the floor.
