From one day to another, with changing the issue-filter slightly, the board configuration in JIRA, my Kanban board went empty. I use the following JQL as filter within the board configuration:
project = "My amazing project" and fixVersion in unreleasedVersions() ORDER BY priority DESC
The above filter does not work. What is working though is
project = "My amazing project" and fixVersion = "v1337" ORDER BY priority DESC
Interestingly, the first query works in JIRA's issue explorer and gives me back the 11 results I expect. As you see in the screenshot below, I have no quick filters enabled, neither do I have any sub-filter added nor am I hiding any older issues. Where did all the cards go?
I am using Atlassian Jira Project Management Software (v8.2.3#802003-sha1:5986657) and I am not administrator of that installation, only of the project.
