Why do my issues disappear from Epic Swimlanes in JIRA?

Question

I have issues that show up in my JIRA project's backlog page, but they disappear when my board is using Epic Swimlanes. If the board is configured to use any other swimlane option, these issues appear on the board.

Answer 1

This bug has been in JIRA for almost a decade. Every JIRA board using epic swimlanes is quietly hiding all issues linked to any epic that isn't included in the board filter. It's also impossible to use JQL to query for the epics associated with a set of issues so you might include them in the board, which means epic swimlanes are effectively broken for everyone (keep your spam comments advertising paid add-ons to yourself, please).

Answer 2

Encountered this issue myself. The solution I found was to edit to query to include the Epic in the board filter explicitly using JQL, and then using the sub filter to remove it again.

Seems to allow the tasks to then appear.
