Bedtime app override does not work consistently

First, I'm going to voice my displeasure that the bedtime app moved from the Clock app to the Health app. WHY APPLE??

Second, my sleep schedule is all over the place so I'm constantly overriding my alarm directly in the Clock app. I have it set for 7am (via the Health app) but sometimes I change it to 6am, or 6:30am, or 7:30am the night before, depending on when I need to be up for work. On 3 separate occasions since the upgrade to iOS 14, I changed my alarm from 7am to 6am and my alarm woke me up at 7am. The first time I assumed I did something wrong. The second time I was suspicious. The third time... I feel pretty confident that this is a bug. I'm usually updating my alarm after 10pm, but always before midnight.

Has this happened to anyone else?
