Why does "Turn on Lights with Motion" keep resetting to "On" position

I would like to turn off the lights to my spotlight cam for all motion. My three motion zones for lights are off. I toggle the "Turn on Lights with Motion" to the "off" position then hit "Save". When I leave the screen and then return, the"Turn on Lights with Motion" is back in the "on position. How do I keep the lights from coming on when motion is detected. Some might ask why I want to do this. For this particular camera's location I want to.
