Wordpress PHP复制拇指

我对php不是很熟练，但我相信这一节中的某些内容会导致我的Fancybox图像重复。

当Fancybox打开时，用户可以使用Next和Previ链接，但每个图像会复制两次。我已经用另一个灯箱代替了fancybox进行了测试，但问题仍然存在。

有人看到这个问题吗，有什么想法如何修复或破解它吗？

        'category__not_in' => (array) get_option('evolution_exlcats_work')
    ) );
    $recent_work_query = new WP_Query( $recent_work_args );
    while ( $recent_work_query->have_posts() ) : $recent_work_query->the_post();
