Supervisors approval

Content

I set up a ILT and the enrollment I checked the box that it needs a supervisors approval.  Testing it I noticed my manager received the email notification and she approved me.  I then received an email saying I have been nominated for the enrollment and I will be notified when an Enrollment Administrator approves you. 

When the supervisor approves why doesn't it automatically generate an email to the employee to say you are approved?  I as the administrator has to go in and approve the employees?  Is there a feature I need to turn or off so once the supervisor approves the employee will not be nominated just automatically approved?
