I have had this happen once or twice. What happened is it probably didn't register your settings.

If you shut your car off and put your key back in, chances are on startup settings are just fine.

If it happens multiple times, chances are the battery in your FOB is dead. Your car charges it every time you put the key in, and if the battery dies you could lose the settings since it would take a long time to recharge and read them.
