When setting up two iCloud accounts on iCal, one of them displays as "p03-caldav.icloud.com" and the description is not changeable

I am trying to display mine and my wife's iCloud calendar's in iCala, which is easy to setup, however once both accounts are active mine displays as "iCloud" and hers displays as "p03-caldav.icloud.com" I have tried using the "edit account" button which links me to the control panel, however the changes made there are not reflected in iCal, even after a restart.
