What is wrong with my sleep tracker

[AC Question]

When I wake up and check my sleep tracker on my gear fit 2, it has gaps between sleep patterns that show white. Like I am awake or up and not asleep. Gaps are up to 2 hours long. I know I am not sleep walking and it doesn't show any steps. Confused.
