Example of defining PMPro Register Helper Fields Synchronized to BuddyPress XProfile Fields

pmprorh-init-buddypress-fields.php

<?php
/**
 * Based on the Register Helper example.
 * We've added a "buddypress" option for each field
 * set to the XProfile name we used when setting up
 * the fields in the BuddyPress extended profile.
 * If the PMPro BuddyPress Add On is activated
 * then the fields will be synchronized.

Hi there,
I used a similar code. However, if you set the porfile as true it generates extended profile field besides generating a field in profile. So, it duplicates itself. Besides, using profile=> 'only_admin' or 'only' somehow brakes the code. I tried 'profile=>false which solved the duplicated field in profile and changed profile field option from everyone to me within the buddypress profile field itself. Yet it does not work. Profile fields are visible to all. Any oslution?

comma needed in line 37 after 'referral'
'buddypress' => 'Referral' // XProfile Field Name <-- !!!
