Sleep Mode Bug

So, last night I noticed that my Epix 2 had randomly exited sleep mode, so I turned it on manually and everything was fine -- or so I thought.

But today I noticed that it hadn't left sleep mode one hour after my set wake up time. I ended sleep mode, fiddled around in the glances, went back to the watchface and boom, it was back in sleep mode. I restarted, did a hard reset and after each restart it's right back in sleep mode. If I go into any activity and leave, sleep mode is back on. My Fenix 6 had a similar bug, but it wasn't that bad and it rarely happened.

Any thoughts?

Update: Apparently, my watch thinks it's Saturday already, because sleep mode turned itself off after 09:00 (which is my weekend wake up time). What the hell.
