在列表页面 num 去定点查询咋失效了

模板标签里面

请问下 在列表页面 num 去定点查询咋失效了，一个别表分页两块。A部分调用3个，B部分调用从第四个内容开始总计8个。现在是上面A部分3个没问题。但是下面B部分列表的8个跟上面3个重复。

代码如下

  {module catid=9 order=updatetime   thumb=1 num=3}
            <li>
                <div class="libox jump">
                    <a href="{$t.url}" class="img"><img src="{dr_thumb($t.thumb,374,249)}" alt=""></a>
                    <div class="txtBox">
                        <div class="MianTitle">
                            <div class="sen"> news</div>
                            <h3 class="h3"><a href="{$t.url}">{dr_strcut($t.title, 20)}</a></h3>
                        </div>
                        <div class="txt">
                            {dr_strcut($t.description,40)}
                        </div>
                        <a href="{$t.url}" class="more">查看详情&gt;&gt;</a>
                    </div>
                </div>
            </li>
 {/module}
 -----------------------------------------------------------------
 {module catid=9 order=updatetime  num=4,8 page=1}
            <li>
                <div class="list-bo layui-row layui-col-space30">
                    <div class="list-box-img jump layui-col-md2">
                        <a href=""><img src="{dr_thumb($t.thumb,167,106)}" alt="{$t.title}">
                        </a>
                    </div>

                <div class="list-box-txt layui-col-md10">
                        <h3 class="h3">
                            <a href="{$t.url}">{dr_strcut($t.title, 20)}</a>
                            <p class="time">{dr_date($t._updatetime, "Y-m-d")}</p>
                        </h3>
                        <div class="txt">
                           {dr_strcut($t.description,80)}
                        </div>
                 </div>
                </div>

            </li>
   {/module}
