当我将wp_query与'post_type'=>array('test','test')一起使用时分页

当我使用2或3种不同的post_类型时,我无法进行分页。这只显示2个帖子,分页显示,但当我点击它仍然显示相同的2个帖子。

<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1 ?>
<?php
$args = array(
    'post_type' => array('pt1','pt2'),
    'posts_per_page' => 2,
    'order' => 'DESC',
    'orderby' => 'date',
    'paged' => $paged
);
$general = new WP_Query( $args );?>
<?php while($general->have_posts()) : $general->the_post(); $imagen = get_the_post_thumbnail_url()?>

    <div class="vc_col-12 vc_col-lg-6 float-left post-loop">
        <a href="<?php the_permalink(); ?>">
            <?php the_post_thumbnail(); ?>
            <h3><?php the_title(); ?></h3>
        </a>
        <p class="text-muted"><i class="far fa-calendar-alt"></i> <?php echo the_time('d'); ?> <?php echo the_time('M'); ?>  </p>
        <p><?php the_excerpt(); ?></p>
    </div>
<?php endwhile;?>
<ul>
    <li><?php  previous_posts_link('&laquo; previous', $general->max_num_pages); ?></li>
    <li><?php next_posts_link('next &raquo;', $general->max_num_pages); ?></li>
</ul>
<?php wp_reset_postdata();?>
