Not sending Billing information to Mailchimp

Hello!

Fields [BPHONE] [BADDRESS1] [BADDRESS2] [BCITY] and [BZIPCODE] are not been sent to mailchimp.

All these Merge Fields are already created in Mailchimp as TEXT fields.

Here is the recipe:

function my_pmpro_mailchimp_listsubscribe_fields( $fields, $user ) 

{
	$new_fields =  array(
		
		"BPHONE" => $user->bphone,
		"BADDRESS1" => $user->baddress1,
		"BADDRESS2" => $user->baddress2,
		"BCITY" => $user->bcity,
		"BZIPCODE" => $user->bzipcode,
                    
		/**
 * and others
 */
		
		);
	$fields = array_merge( $fields, $new_fields );
	  
	return $fields;
}

add_action( 'pmpro_mailchimp_listsubscribe_fields', 'my_pmpro_mailchimp_listsubscribe_fields', 10, 2 );

/**
 * Tell PMPro MailChimp to always synchronize user profile updates. By default it only synchronizes if the user's email has changed (optional).
 * Requires PMPro Mailchimp v2.0.3 or higher.
 */
add_filter( 'pmpromc_profile_update', '__return_true' );

I had add a new member. This is the log file:

        )
