Anytime I add assignees to my filter query, the "create sprint" button grays out. As long as I leave it to "project = xxx AND fixedversion = xxx ORDER BY Rank ASC it will work. Adding any kind of syntax regarding adding assignees even when narrowed down to a single person "assignees in (one_person)" and that one person is the project admin within the project roles, the create sprint button grays out until i add him to the JIRA admins group long enough to create the sprint. I remove him from JIRA admins and the sprint is created, but button is grayed out again. Been looking and looking for best practices, known issues, etc regarding this. Just curious if anyone has successfully added a non JIRA admin assignee to their filter query and "Create Sprint" button is still available.
