Phone Field Not Retaining Data

Hi,

I have set up the Content Profile Module and have the address and phone fields set up and using "use this content type as a content profile for users". When editing my profile through "My Account" I am able to save new address data but when I enter a phone number in the phone field and 'Update Address' the number is not displayed in the address profile and when I go back in to edit it the number has not been retained like the other address information has.

For info I have configured the address fields as follows:

Address Name -> Normal
Street Required
Additional -> Normal
City -> Required
Province -> Required
Country -> Required
Postal code Required
Primary Address Checkbox -> Normal
Phone -> Required
Fax -> Normal

Using Drupal 6.4

Cheers
