When i create a maintenance periode, sometimes during this period, a trigger fires. If i aknowledge the trigger during the maintenance period, and deletes the period when my maintenance is done, it escalates, paying no respect to my action condition that states: "Event acknowledged = "Not Ack""

My action is conditions are:

Label Name Action
(A) Maintenance status not in "maintenance"
(B) Trigger value = "PROBLEM"
(C) Trigger severity = "Error"
(D) Host group = "DanDomain escalations"

And for the operations field:

Event acknowledged = "Not Ack"
