Trying to mark an epic as "Done" in the release board but get this error "This issue cannot be edited because of its workflow status.". There are two stories under this epic which are closed as "won't fix/duplicate" and are not associated with a sprint. The epic is marked with a (still open) fix version.
Not sure this is important but a bit of background: Originally, I closed the Epic out as "won't fix/duplicate" in the jira item editor and got the "This issue cannot be edited because of its workflow status." error. So, I then changed the closed status to "fixed" (again in the jira item editor) thinking this would change the workflow status...it did not.
