Customize and edit your contact labels (types of Phones, Addresses, and Emails) by choosing Daylite -> Preferences... -> Labels. 

In Daylite 3.5/3.6’s default setup, there are three types:
Phone Numbers, Addresses and Electronic Addresses

Customize, add new, or delete unwanted label names for each of these menus by clicking the appropiate “+” (add) /“-” (delete) buttons.

Please note that as of Daylite 3.5, the "Locations" label preference has been removed.
