I've been banging my head against the wall on this one. I have an extra sprint showing up at the top of my work board in JIRA Agile despite the fact that the filter for the board explicitly has AND sprint NOT IN (<sprint #>). I've done all kinds of searching to find any issue from that sprint that somehow matches my board's filter, but I cannot find it.
I imagine there's some subtlety with the parent issues/subtasks or something along those lines, but I cannot figure it out. Does anyone have any ideas of things for me to check?
