Customize Email/Phone/Address Labels:
If you want to customize the email/mobile phone/address labels, then you need set that up in your directory before you import the data. This is really helpful for directories that have "family" type entries and you want to create "His Cell" or "Her Cell" etc. Go to Manage Directory / Customize Labels. You can add new labels and delete any labels that you do not need. If you want to change a label, just delete it with the red x and then create a new one. When you go through the import process, all of the fields in the Existing Labels will show up as choices to match to your columns.
