I am sure there is a simple explanation/solution (chasing Zebras tends to happen in these situations) but never assume if a switch works in one direction it will also work in another direction. I have come close to losing my mind trying to diagnose issues with various combinations of throws and polls - throw in illumination options (backlight always on, backlight keyed to nav lights, up on, middle off, down on, etc.) and it could send a dummy like me to the funny farm.
Good luck and let us know the outcome.
