Pedometer

I have the icon for the Pedometer on my watch face. I touch it to see how far I've gone. But starting a few days ago, it only shows me the distance that it had been last time I looked at. Any new distance does not show up unless I open the pedometer app on my phone, then it shows the distance on my watch.

Why would this have started? Did apple change something in the software? Or could I have accidentally reset something? If so, what?

Speaking of distance, is there anyway to reset the Activity Rings? They are too low.

Thanks
