February watch challenge glitch

For my February challenge I had to burn a certain amount of calories. As of 2/28/18 I was a couple 100 away from hitting my goal. My calorie count decreased about 4,000 calories last night and got stuck on a number and didn't show I was burning any calories for the rest of the day. I worked out extra and longer this month to hit the goal and now I didn't hit the goal. I didn't receive the badge 😠 Anyone else have any issues with this? This is super frustrating.
