I have the simplest of queries for my board - "project = myCode ORDER BY Rank ASC", yet a particular epic is not showing up in the epics panel.
So far I've only tracked down a single one like that.
Is there some additional filtering behind the scenes that is making that one invisible? I can see it in the list of issues in the filter query, it's just not showing up in the epics panel. It's not in the DONE status.
I created a kanban board with a similar result - this item is not in epics panel, but when I switch off epic panel in the kanban board it does show up in the list.
