Forerunner 165 Missing Morning Sleep / Incomplete Sleep Tracking

i recently bought garmin forerunner 165 music, i am using it in doha, i want to mention a sleep tracking issue, in my routine i usually getup with sunrise have half an hour prayers then sleep again for almost two hours, my garmin watch properly tracks my sleep before sunrise but it completely misses the second 2 hours set, it does not even detect it as nap,rest or sleep.

is it possible to solve this issue?
