Let me be honest - it's not a serious defect and I do not want to waste my time on ping-pong with Garmin Support. I'm almost seven years with Garmin with many different devices (multiple watches, Edge, Varia, Virb, inReach, etc), and my own opinion - other than replacing broken devices they are mostly useless.
It has resolved by it's own a day later (probably post data ingestion to garmin connect). I don't care about this defect. It is more of a fun defect - having +137 in body battery during the night.
