Lock setting seem to change

[NormVA]

I set "walkaway lock" in the car. I also wanted to check locking the car from the screen icon. I locked the car with the screen icon (after I had opened the door). When I went back to the car, walkaway lock was no longer selected. It seems that the same thing happens, if I lock the car from my phone. Am I doing something wrong that allows this setting to change?

I reset walkaway lock and it worked when I left the car. Not sure if it will work next time.

Thanks, Norm
