Sleep Modus - Time ist missing

[hoermal]

I have got a problem with the sleep modus. When I go to bed I start it and when I woke up I stop it - if I calculate the time is different to the time on the band. Every night I am losing about 1 hour - where is it? Does anybody have the same problem.
I can not look in the App, because when I would like to open the sleep data, the app crashes all the time.
I am using a Lumia 630 in Germany.

Greetings

It's called "Actual sleep" - the total amount of time the Band sensed you were asleep. It subtracts out the time it takes to go to sleep and any awake time during the night.

If you can get the app working, you can see the graph. That's much more telling.
