No notifications after turning on do not disturb

Been using the watch for a few weeks now and one thing I’ve noticed is that if you turn on do not disturb on the watch for a few hours , after you turn it off you don’t get notified

I’ve turned on dnd for 1 hour and i was able to get notified still but if I turn it on for longer , I don’t get any notifications

When I go to sleep , I’ll turn on dnd and when I wake up and turn it on I don’t get notified. So after 8 hours of having dnd on I don’t get notified after turning dnd off . I have to restart the watch to get notified

Anyone else noticed this behavior ?
