Need to rename and delete contact group
I have two contacts lists in my icloud: "all contacts", and "contacts(2)". Contacts contains all the dupes, contacts (2) is the good list. I was able to rename "contacts(2)" to "all contacts", so I now have two groups named "all contacts". The instructions for how to delete a group seem not to work with the "bad" all contacts" group. How do I get rid of that one, and keep the one that I renamed from contacts(2) to all contacts?
iPhone 5, iOS 7.0.2
