Health app alarm glitch?

Hello,

I use the health app bedtime alarms very often. Lately, I noticed a possible bug where it seems like the app doesn't register individually scheduled days anymore. For example, my default sleep schedule alarm is set for 3 am through Tuesday to Thursday. Yesterday I set my wake up time for the next day to 4 am instead of the usual 3 am, but the app still woke me up at 3 am. On sunday and monday, even though I set individual alarms for those days, neither of them went off, which I assume is because my default schedule doesn't have alarm set for sundays or mondays. This is weird because I used to schedule individual days all the time and the alarms would work properly. This is the first time I've ever experienced this. I did not change any of the settings that could've influenced this, like timezone, before this started. Is this a new feature of the app or a bug? How do I fix this?
