Watch goes to compass mode. What gives?

I have a fairly new Apple Watch, series 7. I just purchased it in July. Now, after 15-20 seconds of inactivity or when I get up and go for a walk, my watch-face switches to the compass face with "footsteps" at the bottom right of the screen. (see images below. I didn't move my arm.) I can get back to my watch-face screen by clicking the crown, but it's very frustrating for the watch not to stay of the standard watch-face screen. I've tried powering off and on again, but that doesn't help. Is anyone else experiencing this problem? What can I do to stop it?
