Active minutes, exercise, and calories disappeared from Fitbit tracker

[Ap89]

Hi 

I went to the gym this morning and, as usual, I manually started the treadmill in the tracker. When I finished, I stopped it and looked at the summary. After this, I manually started a workout in the tracker and, after I was done, I stopped it to look at the summary. Last time I looked the tracker, it showed 44min of activity, and around 700cal burned. Now, when the notification on my phone appeared for 'almost to your exercise goal', I opened the app just to see that the activity was not there, nor the active minutes or calories burned. I looked back to my fitbit, and the information was also gone (it only shows 9min of activity and around 500cal burned). I am now wondering, how can this happen?

Thank you for the feedback,
