Apple Watch didn’t record exercise ring

The original post for this was by someone else in 2015, and I tried resetting calibration on my watch as that answer suggested, but I am still having this problem in 2019 after the recalibration. I recorded an outdoor walk in the city yesterday for 46:12 minutes, going 1.83 miles, which was recorded as an outdoor walk on the app, but my exercise ring only shows 1 minute during the walk. Q1: is there a way to correct the exercise ring manually? Q2: how do I get the exercise ring to record accurately?
