使用layui做弹出层，关闭窗口无法隐藏，这是是什么原因呢？

Question

使用layui做弹出层如图一，关闭窗口后，div又显示在了页面中如图二，正常情况是关闭窗口也隐藏，这是是什么原因呢？是不是导报包不对，求大佬指点

<div id="add-main" style="display: none;">
              <form class="layui-form" id="add-form"  action="">
                  <div class="layui-form-item center" >
                    <label class="layui-form-label" style="width: 100px" >当前密码</label>
                    <div class="layui-input-block">
                      <input type="text" name="name" required value="" style="width: 240px"  lay-verify="required" placeholder="请输入当前密码" autocomplete="off" class="layui-input">
                    </div>
                  </div>
                  <div class="layui-form-item">
                    <label class="layui-form-label" style="width: 100px">新密码</label>
                    <div class="layui-input-block">
                      <input type="text" name="type" required  style="width: 240px" lay-verify="required" placeholder="请输入新密码" autocomplete="off" class="layui-input">

                  </div>
                  <div class="layui-form-item">

                  </div> 
              </form>

设定了yes函数，需要自行关闭窗口

 yes: function(index, layero){
    layer.close(index); 
  }
