I tried to find a similar issue on the forums back wasn't successful. I tried to use my watch during Brazilian Jiu-Jitsu training today.
It looks like it logged the amount of time correctly overall, and tracked heart rate but then it shows only 2 calories burned and only 1 minute on some of the screens but 94m.
Main screen 94m, 2cal burn, 74active min
When the exercised is selected to show the weekly log it displays as 1m, 2cal, 74active min.
