Sunset/Sunrise alert issue after factory reset.

Hi All,

I have been using Sunset alert (set to 1 hour before sunset) on my FR255 for quite some time. Recently, because of watch restarting during workouts, I have followed some recommendations ad restored my watch to default factory settings and re-applied all my custom settings again manually without using backup restore.
However one I have problems changing settings for sunset/sunrise alarm notifications. It is actually impossible now to TURN OON notification for sunset - the switch is there, but changing it has no effect, it remains turned off when I reanter that screen. For sunrise however its the opposite - I cannot TURN IT OFF, I can only change the time for notification. The same behaviour in both, watch menu and Garmin Connect app. I am running software version 21.22. Looks like a system bug to me.
