多级栏目循环咋调用二级栏目的SEO描述呢？？
我写的方法调用不出来

{category module=share pid=10 return=c1}
            {category module=share pid=$c1.id return=c2}
            <div class="col-3 col-xxl-3 col-xl-3 col-lg-4 col-md-4 item">
                <div class="picimg">
                    <a href="{$c2.url}">
                        <img src="{dr_get_file($c2['thumb'])}" alt="{$c2.name}">
                    </a>
                </div>
                <div class="info">
                    <div class="title">{$c2.name}</div>
                    <p>{$c2['setting']['seo']['list_description']}</p>
                </div>
            </div>
            {/category}
            {/category}

后台已经给了SEO内容 单就是没出来
