Administration

I have installed gibbon successfully. However, i have added teachers and students in user admin and set them to FULL and have set up all of these:
Manage Days of the Week
Manage School Years
Manage Special Days
Manage Terms
Manage Year Groups
I have tried to set up a roll group but only the administrator user is available to add to that role group.
All users appear in the user admin menu but not in the People or Staff lists.
Please advise…what am i doing wrong?
