Echoing this. This has happened to me a few times as well. I reported it to my service advisor over txt and all he said was make sure software is up to date. Of course that response was not helpful, but its a rare enough situation for me that I let it go.
I even had a different situation once where the trip meter reset as if it charged at the scheduled time, but it hadn't actually charged. This was with the current 2.3.0 version. Same answer from them to make sure software is updated and do a soft reset. At this stage, i just try to be diligent about checking the SoC in the morning. This has only happened once so far though.
