Why am I getting multiple repeat alarm emails for the same probe or sensor?

Why am I getting multiple repeat alarm emails for the same probe or sensor?

What is happening is that the same probe is going in and out of an alarm state multiple times without the alarm being acknowledged. Each time the probe goes into the alarm state it is counted as a unique alarm. An email will be sent (or re-sent according to the alarm repeat setting) for each unique alarm that is not acknowledged. As an example: On the same probe a high temperature alarm is detected at 12:08, and then another is detected at 12:38; both are sent out when they occur, and then also every 30 minutes until they are acknowledged. Despite being from the same probe, both are treated as distinct alarms and sent (and re-sent) out. This causes two nearly identical looking alarms to be sent out at 12:38, and every 30 minutes after that.
