Why does the Charge 3 count steps when I'm riding my bike. It automatically tracks my bike ride (25 miles, which was accurate), but it showed that I had 15,425 steps too. My arm is not moving while I'm riding. There was a setting on my previous fitbits that eliminated duplicate activities. For example, if I tracked a run, steps were not counted at the same time. I can't figure out how to shut off steps while riding.
