Redmine

I want to add "required" permission to my custom field for specific role and tracker. I'm selecting only related role and tracker to do it but it doesn't work. Field permissions table showing my "required" selection after saving process but this field is not showing as "required" with red "*" symbol on issue page.

If I select all roles on "field permissions" table, it works. But I don't want to add "required" permission to all roles.
