Thunderbird address book nick name hascontact full name, name field has contacts email address

I imported my address book (.csv export from windows live). The Nick Name field has the contact name, the name field has the contacts email address. It make creating email difficult, all I can see is the 'name' filed, so I can't tell what the contacts full name is. Is there a way to re-arrange the fields in the address book or be able to display nickname when writing an email with address book displayed
