Amazfit screw up with DST?

Did anyone else’s Amazfit screw up Biocharge from DST? (An apparent bug) I woke up initially this morning with a Biocharge of around 80. (Typical, looks normal) Never got out of bed and then fell back asleep for 2-hours. Rechecked my watch/app and noticed that the Biocharge got reset back to 0 and then increased back to around 30 (new baseline for the day) after the 2-hours of additional sleep. Disappointing as I’ve been really happy with my Balance 2 up until this. Thanks.
