I have a Kanban board that does not display two issues associated with an Epic that display when I run the base query (aside of the board and within the board when no swim lanes are added). When I add any swim lane (by Epic) these two issues are no longer displayed. They do display when I make the swim lane by resource (or anything else). The issues are associated with the Epic and the Epic has a status of "In Progress".
I am hoping that someone can suggest some next trouble-shooting/triage steps. We are running JIRA Server v7.1.2.
