Apple Watch alarm disables itself overnight

Since getting my Apple Watch last year, I’ve used it as my morning alarm, utilizing the sleep schedule alarm. As of two days ago I noticed that the alarm is no longer functioning. When I go to bed, my watch says “alarm set for X:XX” but the following morning the watch is still in sleep mode and says “no alarm set”. I attempted to restart both my watch and iPhone yesterday directly prior to going to bed, I also ensured that both the watch and phone have an alarm set prior to going to bed, but it did the same issue once again.

My watch is running: 26.0.2 (23R362)

My iPhone is running: iOS 26.0 (23A341)
