academic license - adding students to team

I was just upgraded yesterday to the academic status which I thought would allow me to add more than 5 students.

I had previously created a team called CS286 for a course I am teaching. I am trying to create a private project for each student in the course to submit code. I can not add more than x5 students.

Assume I am missing something.
Thanks,
