I have a board with a filter "project=SAND AND labels=BoardTest". When I create an issue via the backlog, the issue automatically gets the label 'BoardTest', which is really nice.

However, when I create an Epic via the backlog (in the left panel), it does NOT get label. And as I do not have labels required in the field configuration, I am not prompted to adding the label. Thus, when the epic is created, it is not shown on my board in the epic panel.
