scheduled charging not working

I recently started home charging and my off-peak hours are from 12am - 3pm. I have scheduled departure off and I set "start charging" at 12am.

Ive noticed that when I first plug in my car around 8 or 9pm, it shows on the car screen that it's not charging and that it's scheduled to begin charging at 12am. But multiple times now I've noticed that I'd check the app an hour or 2 later (before 12am) that the car has already been charging for a while! Anybody else running into this issue?
