Walking Excercise Time Recorded But Not Counted In Rings

I haven't gone out for a walk since the last Watch OS update. This morning, I walked mostly non-stop for almost two miles. I used the Workout app and selected "Outdoor Walk," as I usually do. At the end of my workout, it recorded a time of 36:38 minutes. But the rings only show about 14 minutes of that time. As I stated earlier, the mileage recorded was 1.98. Is this a bug in the latest Watch OS update? This is the first time the stats haven't matched the rings.
