Magento 表中的费率不适用于免费送货

我需要显示一个货运公司的免费航运选项列表，即时通讯使用 扩展“Webshopapps矩阵费率”适用于价格

但当运费为0（免费）时，它就不起作用了（见链接中的图片）

这是密码

}

有什么线索吗？

我不知道你想达到什么目的，但我想为不同类别提供不同的运费价格，运费价格是篮子中类别的最大值，高于一定价格的免费运费（还有一个类别，礼品券，如果是单独的话，也可以免费运费），不同国家的运输价格也不同

---

我使用并修改了它，以提供我想要的详细规则。

打开共享图像文件。如果价格达到“0”，则不显示交货类型。如果我将运输价格设置在0以上，一切都会正常工作。
