PLEG action fired erroneously?

Plugins & Plugin Development Program Logic (PLEG)
1

This instance of PLEG (used for my alarm triggers/conditions/actions) was in BYPASS and still managed to trigger an alert:

Unit Notification <noreply29@notification.mios.com>
5:20 PM (10 minutes ago)

to house 
Your trigger "Alarm Tripped Home" occurred.

The originating device ID:59 PLEG Alarm in room:

The ID is: 257384235
Code: ConditionSatisfied Value:AlarmTrippedHome

The condition is:

Name	                Repeat	Expression
AlarmTrippedHome	No	        (StaySet OR GoodnightSet) AND (FrontDoorTripped OR GarageDoorTripped OR RearDoorTripped)

However, the input hadn’t been triggered:

StaySet	         MultiSwitch Switch 2 is turned on	false	    2014-06-11 16:19:19.633	2014-06-11 16:55:34.403
VacationSet	 MultiSwitch Switch 4 is turned on	false	    0	                                        0

(MultiSwitch switches 1-5 are a group, and Switch 1 is turned on, the rest are all off…)

Even the notification apparently wasn’t sent… ?!

Name	                 Description	                                                                 Users	        Last Sent
Alarm Tripped Home	 PLEG Alarm has satisfied condition: AlarmTrippedHome	 tomasone	2014-06-11 16:53:16.28

How could this have happened? What (if anything) am I missing?

Edit: I just got another notification that it was tripped again. I have turned on debug mode. Here is the current input status, taken after that second notification:

So StaySet and VacationSet haven't been true since 16:55, yet I got alarms at 17:20 and 17:36.   Could this be a serious delay in alerting?

Bypass only turns off the Actions … If the alert was part of the action it should not have happened.

It does not turn off Notifications (A notification on the PLEG when Condition YourConditionName is satisfied).
