 Empty values should not be included in the report. Otherwise, the report
 will be cluttered with empty values.

 Use the following code in `mu-plugins` to reproduce:

 {{{
 <?php
 function exporter_1( $email_address, $page = 1 ) {
         return array(
                 'data' => array( array(
                         'group_id'    => 'group-1',
                         'group_label' => __( 'Orders', 'woocommerce-
 services' ),
                         'item_id'     => 'item-1',
                         'data'  => array(
