Filtro Magento 2 não funciona enquanto a coluna Custom foi adicionada na Sales Grid Using Ui Component

Adicionei coluna Personalizada track_numberem vendas >> Grade de pedidos no back-end.

<vendor_name>/Sales/view/adminhtml/ui_component/sales_order_grid.xml

<?xml version="1.0" encoding="UTF-8"?>
    <listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <columns name="sales_order_columns">
        <column name="track_number" class="<vendor_name>\Sales\Ui\Component\Listing\Column\OrderGrid">

O código acima ajuda a recuperar os dados da trilha e anexar a coluna à grade Order, mas para classificar ou filtrar nesta coluna personalizada, preciso substituir o modelo de coleção de grade \Magento\Sales\Model\ResourceModel\Order\Grid\Collection.php

<?php
/**
 * Copyright © 2013-2017 Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace <vendor_name>\Sales\Model\ResourceModel\Order\Grid;

use Magento\Framework\Data\Collection\Db\FetchStrategyInterface as FetchStrategy;
use Magento\Framework\Data\Collection\EntityFactoryInterface as EntityFactory;
use Magento\Framework\Event\ManagerInterface as EventManager;
use Psr\Log\LoggerInterface as Logger;

/**
 * Order grid collection
 */
class Collection extends \Magento\Sales\Model\ResourceModel\Order\Grid\Collection
{
    protected function _renderFiltersBefore() 
    {
        $joinTable = $this->getTable('sales_shipment_track');

        $this->getSelect()->JoinInner($joinTable.' as ordertable','main_table.entity_id = ordertable.order_id', array('track_number', 'tacking_created_at'=> 'ordertable.created_at'));

        parent::_renderFiltersBefore();
   }
}

Tudo corre bem, mas por causa dessa coleção, junte-se à sales_shipment_tracktabela. Ele cria um erro de violação de integridade no filtro padrão, enquanto temos o mesmo campo created_atou statusporque obteremos a mesma coluna / campo nas duas tabelas.

O problema é como aplicar o filtro na coluna personalizada sem afetar a coluna padrão?

Qualquer ajuda seria apreciada.
