Epic panel lists no epics

[Pradeep Chandra]

I created a board to have a Icebox like approach. So, I created a post-function on for my workflow to create issues with label = Icebox. Now, I created a board to use that filter. 

project = ORP AND labels = Icebox ORDER BY Rank ASC

when I use this filter, my Epic panel is enpty. It doesn't show my epics. It does list all the stories and tasks labelled as Icebox. Also, if I add the Epic link column to the list, Epics show up too. But my Epic Panel is empty

Are your epics also labelled Icebox?

[Pradeep Chandra]

no, the epics are not labeled as Icebox. Do I have to?

My basic idea of labeling the stories is so that, the ungroomed stories are not visible to everyone, I want them to be visible only on my Icebox board.
