Issues with read/write permissions in Tenants

Okay so I’ll explain my issue in detail, I am creating 2 users i.e dashboard_edit_user, dashboard_read_only_user, such that the dashboard_edit user has access to read and edit dashboards while read only user has only read access, but when I have made some configurations where, edit user works properly but read user is able to edit dashboard. Earlier I was unable to create tenant this time I have created tenant via dashbiard UI. These are my conf files please help me resolve this.

Please try the following changes in roles_mappings.yml and re-upload your configuration using

  reserved: true
    - "dashboard_edit_user"

  reserved: false
    - "dashboard_read_only_user"
