Huh. That's strange! One thing I've noticed when changing settings in general- *make sure you're in the driving profile and not easy entry* when you make adjustments. In other words - if you fixed the setting but were in your easy entry profile as soon as you step on the brake pedal it switches to your driving profile that has its own settings. If the driving profile has the problem setting then it won't be fixed. How it got messed up in the first place is anyone's guess.
Hope it is that simple. Do report back when you get it fixed, I'm curious.
