Postal Code and Phone No. are not displayed in CiviCRM Group Member List after users register this info to a CiviCRM Profile

If you create a CiviCRM Group and CiviCRM Profile for users to fill out when volunteering for an event, the phone number and zip code data entered during user registration will not be displayed from the CiviCRM Group Member List: civicrm/group/search?reset=1&force=1&context=smog&gid=7 (The hyperlink points to a listing for the group, MFA Volunteers)

30.Notice that the Postal Code & Phone No. are not displayed for the admin user you just volunteered. (This user should
be added to the group)

Notes
1. If you click Volunteer Admin on the event you volunteered for in Step #25, you will see the same phenomenon. Based
on this, I suspect the defect is in volunteer not CiviCRM.
