Charge 2 activity data changed

[Mammyk28]

I walk 6 days a week (6 miles 3 days a week & 4 to 5 miles the other 3 days). Up until today I though my charge 2 was tracking okay. Most days I meet all my miles, calories, minutes & floors.  Today I did 16,353 steps with 1 hour & 6 minutes at peak heart rate zone, average heart rate was 136bpm. According to my dashboard I only burned 56 calories and have zero active minutes.  In looking back at the past week or more now a lot of my data has been changed. All of my calories burned no longer reflect the correct numbers. I know they are changed because when I would sync my charge 2 at night I would fill in all the circles on the dashboard and get the fancy green screen. Now when I look back my circles are no longer fully filled in and the data is changed. I haven’t done anything different so I have no idea why this is happening.

@Mammyk28 Welcome! It's great to see you around! Sorry for the delay in my reply.

Let me help you with your activity data. This is odd. Have you logged any activities on your account? Could you share a screenshot of your daily totals and the activities area? Do you have any third party app linked to your Fitbit account?

I look forward to your reply.
