Sleep tracking bugs

Hi,

My Garmin Fenix 5 plus has issues tracking my sleep. To summarize:

1. It doesn't consider sleeping during the day as sleep even if I sleep for 4 hours.

2. Last night, my battery went off around 5 am, so I put my watch on charge when I woke up and only wore it again around 9:30 am. My Connect app recorded all this time as a deep sleep! 

 

Is anyone seeing the same behavior?
