Alarm Clock sounds quietly for about 2 seconds and persistent sleep schedule issue after iOS 18.3.1 update

I turned the phone off then on. Focus is off. I don’t use sleep schedules in Health, however when I turned the alarm button under the sleep schedule on, the alarm function went from not working at all to a quiet 2 second performance. I tried to delete the sleep schedule, but it is persistent. I simply want a functional alarm, not a bunch of bells and whistles.
