检查发现，对应实视图文件对应字段错误，需要将\app\admin\view\website\category\edit.html文件
<div class="form-group">
<label for="c-type" class="control-label col-xs-12 col-sm-2">{:__('列表模板')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-list_tpl" data-rule="required" class="form-control selectpicker" name="row[diyname]"
value="{$row.list_tpl}">
{foreach name="listTplList" item="vo"}
<option value="{$key}" {in name="key" value="" }selected{/in}>{$vo}</option>
{/foreach}
</select>
</div>
</div>
改为
<div class="form-group">
<label for="c-type" class="control-label col-xs-12 col-sm-2">{:__('列表模板')}:</label>
<div class="col-xs-12 col-sm-8">
<select id="c-list_tpl" data-rule="required" class="form-control selectpicker" name="row[list_tpl]"
value="{$row.list_tpl}">
{foreach name="listTplList" item="vo"}
<option value="{$key}" {in name="key" value="" }selected{/in}>{$vo}</option>
{/foreach}
</select>
</div>
</div>
