"Setting shutter duration resets relay pin to be a servo"

Hi.
Every time I change the trigger duration or any other parameter on the Camera Guimbal config page the CAM_TRIG_TYPE goes to cero and the output of the selected Aux pin start to work in Servo mode. No mater if it was previously set to cero (Servo) or "1" (Relay). So the camera stop working until you manualy set the CAM_TRIG_TYPE to 1.

I'm sorry about the image wich I take from the web. It's not a real image from my PC. Im runing the last version of Mission Planner ... I think it's the 3.32.

Start by reproducing the reset on the Camera Gimbal config page while changing trigger duration or another parameter, then trace how CAM_TRIG_TYPE is saved and loaded. Done means changing those parameters no longer changes the selected Aux pin from relay mode to servo mode, while the existing camera trigger behavior remains intact.
