Error: User status is required!

Hello,

On the WooCommerce order page, I’am getting message ‘Error: User status is required!’;
I searched for where the problem could come from…

1 – This hook adds extra fields in checkout page:
add_filter( 'woocommerce_checkout_fields', array( $mangopayWCMain, 'custom_override_checkout_fields' ), 99999 );
In the method custom_override_checkout_fields, we can see that user_mp_status field is not added if all buyers are either and if user meta exists (that’s my case).

if('either' == $this->options['default_buyer_status']):
   if(!get_user_meta( get_current_user_id(), 'user_mp_status', true )):
      $fields = $this->add_usermpstatus_field($fields);
   endif;
endif;

2 – This hook validates extra fields in the checkout page:
add_action( 'woocommerce_checkout_process', array( $mangopayWCMain, 'wooc_validate_extra_register_fields_checkout' ));
The method wooc_validate_extra_register_fields_checkout calls validate_status method.

3 – The method validate_status displays error on my WooCommerce order page because there is no ‘user_mp_status’ field and no ‘user_id’ field in the checkout form.

//get the data
$isset = false;
$value = false;
if(isset($data['data_post']['user_mp_status'])): /* THERE IS NO 'user_mp_status' FIELD IN CHECKOUT FORM : $isset = false */
  $value = $data['data_post']['user_mp_status'];
  $isset = true;
endif;

//in case of edition
$user_to_test = false;
if(isset($data['data_post']['user_id'])): /* THERE IS NO 'user_id' FIELD IN CHECKOUT FORM : $user_to_test = false */
	$user_to_test = get_user_meta( $data['data_post']['user_id'], 'user_mp_status', true );
endif;

if(!$isset && !$user_to_test): 
  //error
  $data['message'][] = __( 'User status', 'mangopay' );
  $data['message'][] = __( 'is required!', 'mangopay' ); /* DISPLAYS ERROR ON WOOCOMMERCE ORDER PAGE */
  $this->send_message_format($data);
  return;
endif;

4 – My solution: adding this code in theme function.php file

if ( get_user_meta( get_current_user_id(), 'user_mp_status', true ) )
	add_filter( 'woocommerce_checkout_fields', 'user_mp_status_checkout_field', 99999 );

function user_mp_status_checkout_field( $fields ) {
	$fields['billing']['user_mp_status'] = array(
	'type' => 'text',
	'value' => get_user_meta( get_current_user_id(), 'user_mp_status', true ),
	'class' => array('hidden'),
  );
  return $fields;
}

Can you confirm if that is a bug or a misconfiguration? If this is a bug, will it be corrected to the next update?
