So I've noticed there is a bug in JIRA. When at first you assign a filter to a board which is private then obviously the board doesn't appear to other users but however if you remove it, it reappears but if you click again on the same board on the board's column it disappears and shows the message attached
. Jumping in between boards is fine but clicking the boards two time shows this message again. Plus it starts happening with every board in the project.
