Missing stop/snooze button on alarm

Hello. Since updating my iPhone to iOS 15 I’ve noticed that the ‘stop’ and ‘snooze’ button have disappeared from my 7am alarm. I normally have the sleep focus on and would normally have the ‘stop’ button appear regardless as I’ve also deselected the option for the snooze button. I’ve deleted all my alarms and have reset them again but it is still the same. The problem doesn’t seem to happen with alarms for other times.
