I recently upgraded to Mountain Lion and implemented iCloud. Everything seems to be working fine, but I noticed that, in the "Groups" list on the left hand side of the Contacts screen, there are two groups for "iCloud", both of which contain the same subgroups (i.e. those that I have created such as Business Contacts, Clients Contact, Family Contacts, etc.). Is this normal? Is there a way that I can delete one of these groups to clean up the screen a bit? Thanks.
