Fenix 6 25.10 - Sleep and Body Battery not working properly anymore

Since my watch updated to the latest 25.10 the overnight sleep and body batter tracking seems not to work anymore. It's the second day in a row where my Garmin thinks I went to bed at 0.30 (1hour later than actual) and woke up at 4.30 in the morning (actually slept 3 hours more). Also the body battery has many gaps in the stress diagram and went up only to 50 even tough I had a good night.

And lastly HFV shows just 1 small line from the middle of the night. Yesterday and today also just 1 straight vertical line at about 02.00 in the morning from 50 to 65ish
