The main gear door actuators are held closed with hydraulic pressure. See attached diagram. If only one door coming down it lends that the system is losing pressure. It could be the door actuator on the subject door. There are no uplocks on the doors as I was reading the print incorrectly.
The main gear actuators are tee connected in with the strut door actuators. Of course there is micro switches that have to be satisfied. Sounds like an actuator on the main door is leaking down.
