Starting yesterday morning, as indicated by the attached pictures my active calories on the "My Day" snapshot of GCM on iOS only shows 10,000. When clicked, the next screen shows a more accurate calorie count for the day and I can't figure out the reason for 10,000 other than a bug.
I had the same problem awhile back. Agreed it is a bug. It's showing your steps in the calories spot. See my thread asking about the same problem. It fixed itself somehow. Don't know how.
