To remove a user from an assigned role inside a project, it is enough that I find his name on the Project Roles page and click on the garbage can icon, as shown in the attached image.
BUT, for a specific user in our JIRA environment, clicking on this icon has no effect! The only way to remove this user from this role inside this project is to enter in the user administration page and edit his project roles from there!
Why this user role cannot be removed in the "regular" and easiest way?
Thanks in advance.
