Calorie counter stopped working!

My active calorie counter has stopped working. Yesterday it stated I had burned a total of 50 calories throughout the day after a 30 min workout and an hour long walk. I usually burn around 1200 calories per day. Same is happening today! I have not changed any settings on either iPhone or Iwatch so its very strange. The stand & workout counters are both working as they should be.

For info:

1. I have the latest software download on both iPhone & iwatch
2. All settings on iwatch are correct to count calories
3. All settings on iPhone are correct

Any help would be greatly appreciated thank you.
