How to remove accounts without licenses

I'm in the Adobe Admin Console and we have an SLP list of users/accounts for Students and an AICUP list of users/accounts for staff/faculty. 

I am able to remove users/accounts from the SLP list that don't have a license assigned (because the student graduated, left the University, etc.), so the list is more true to how many accounts we actually have with assigned licenses. I am able to select an account (check a box to the left of the account) and then an option to remove pops up. 

But I am not able to remove any users/accounts from the AICUP list, there is no box to check to the left of the account like the SLP list and there is no option to select or remove an account from the list. 

Is there something we are missing or something we have to do to clean up that list AICUP of users?
