Workout Prompt to start seems to cause Exercise Minutes to stop recording after workout stop.

I’ve been trying to use the watch prompt to start (and finish) an outdoor workout, on an AppleWatch SE (gen 2). Seems to work well, but then my exercise minutes stop recording, as long as the prompting is enabled. Even stopping it doesn’t work. My exercise minutes stop recording, and several times I’ve continued with vigorous walking and jogging, registering many thousand steps, but the exercise minutes do not change. This is repeatable. When I turn the prompt off entirely, however, things return to normal. My wife’s watch 7 does not have this problem. Ideas, anyone, aside from not using the auto start options? Thanks, Michael
