I'm trying to create a filter that excludes tickets with a label of "Review" or "review", but it is excluding tickets that have never had either of those labels applied at any point in the ticket's history. My JQL is as follows:
project = RC AND assignee in membersOf("Epic PB Application") AND issuetype = Change AND status = Escalated AND labels != Review AND labels != review
Initially I had used the operator "not in"(Review,review), but that was excluding every ticket across the board. When I changed the logic to use the != operator, it picked up some tickets but not all of those which should have qualified. Again, I wish to stress that neither of these labels were ever used in the history of the tickets which aren't getting caught by the filter. What is going on?
