Although this specific user has a role in this project, which can be verified in system's "User management" page, "View Project Roles for User" section, it does not show in the "Users and roles" list in project's setting section. The user still acts normally according to its role in the project, but we are very puzzled by the fact it is not showing on the "Users and roles" page. Other users don't have this problem. Are we missing something here or this is a bug? We tried cleaning caches, restarting jira, double-checked groups and roles.
Thank for any help!
