I have this alarm:

I've made sure the Ack Mode is Auto:

However, when I trigger it, it shows up as Unacknowledged

So what gives? Does Ack Mode Auto not do what I think it does?

Ack Mode Auto will Acknowledge the alarm AFTER it goes back to NOT in Alarm.

With it set to manual, the alarm has to be Acknowledged manually by an operator.

I see. I also poked around and discovered that the "Unused" setting will acknowledge as soon as it becomes active.
