Fitbit issues (losing active minutes and cals)

So I use my Fitbit as a rough guide of calories and mostly use it to track steps but I'm getting annoyed because I take a few bigger walks throughout the day and I notice that my last little walk to finish the 10k/day job ends up being the only activity tracked. And my calories drop way down which makes me pissy because data lol is anyone else noticing issues with theirs?

The past three days my active minutes have not shown up as well. I usually get an extra couple hundred and the past few days it has been less than 100.
