MS Outlook-deleting contacts

Factual Questions
1

I need to delete the Contacts in my Microsoft Outlook. Somehow I have two lists of contacts and the other one is the right one. It is called something else and is attached to the calendar for some screwball reason (I’m sure it was my fault but I can’t explain it). So I need to delete the Contacts then move the other contact list and call it Contacts.

Anyone?

Okay, I have deleted the old contacts by “select all.” Then I moved the other list to Contacts, but it is now a subset of Contacts instead of the main thing. How do I make it the main thing?
