Prosites Newbie...question

Hi all,
This may be a dumb question.
I thought I had things installed correctly but I noticed something that did not seem right.
If I act as a new sign-up (free trial) and login to that new site it is showing my sites...1. the main site (which is mine) and then the actual site they created. When I go back to network admin they are shown as subscribers...I have an account at edublog and it does not do only blog..under my this just a simple on and off switch or did I do something wrong...

Thanks in advance...
