When accessing Security report the term 'Site Default Course Role' is used instead of 'Default role for users in a course'. This could be misleading, especially in combination with the "Default course roles".
Site Default Course Role:
1. Default role for users in a course
2. Default role for users in a course (global) (my+1)
3. Default role for users in a course (site)
Default course roles:
1. Default roles (courses) (my +1)
2. Course Enrolments Default Roles
