I created a filter called "My open issues". But later I wanted to name it with caps like "My Open Issues". Since Jira wouldn't let me rename it, I created a new filter. Then I deleted the first one. The first one no longer shows in the Manage Filters section, but it still displays in the Issues dropdown at the top, under the Filters section. I've tried everything to make it go away, even deleting the newer created version of itself. Nothing I do will remove it from the Filters section of the Issues main dropdown. Is this a bug, or is there a way I've missed in getting rid of it?
