I'm having a real issue with 2 of my Mercury SRS units (updated to the latest version) where each time I go into the "Servo Matching" screen to make slight adjustments to a channel it clears ALL of my gear/doors sequencing that was previously setup.
This has happen every time I do this plus if as I do, use one of the door preset channels for something else (in my case the wheel brakes) it removes this as well.
The effect is that every time I make any servo matching changes I have to go through the sequencer setup of gear and doors - thankfully in my case its only gear and 1 door!
You only need to select and enter into the Servo Matching screen (not even make any changes) and it reset the sequencer.
Can you check please or I could send you a video if needed.
