Since the new Morning Report update, the awake time in sleep tracking is no longer automatic, but is based purely off when I close the Morning Report.
Before the Morning Report release roughly 2 updates ago, sleep tracking was fairly accurate as to when I woke up. If I started moving around, it guessed pretty well that I was awake and stopped sleep tracking.
Now, sleep tracking thinks I am still asleep even if I am moving around, until I clear the Morning Report.
It always puts my awake time as the time I cleared the Morning Report.
