Hi iCal experts, here is my issue :
When I upgraded to Mavericks, I made some changes in my calendars.
I used to have a group of calendars (entitled "Antoine PARASKEVAS" , see the screen copy enclosed) from which I deleted all calendars.
Basically, this group of calendars is now empty, BUT I do not know how to get rid of this group of calendars.
Could you help me, please ?
