using 840; After course ride, press save records a ride with zero miles and zero data since recent firmware update in July. is there a hard reset?

Since the recent update to 21.18, I have not been able to save a ride after following a course.  at the end of the ride, i press the button on lower right, press the finish flag and then the green arrow. What is saved is a ride with all zeros and no data.

Can someone tell me what I'm doing wrong?

Will a Reset fix the problem?
