Google Maps API和Google Maps位置在PHP中显示了不同的位置

我正在将客户网站与Google API集成在一起，我的任务是使用用户的邮政编码（UK）验证用户地址，并使用https://ideal-postcodes.co.uk/来获取地址。。

因此，当用户输入邮政编码时，会将带有用户输入的邮政编码的ajax请求发送到该邮政编码URL。然后从该邮政编码中返回一组地址，然后用户选择其中一个。

现在，该邮政编码URL还返回该特定邮政编码的经度和纬度。对于下一步，我使用了Google Maps API，该API显示了方向，距离以及从源到目的地的路线。

一切正常，但是对于某些邮政编码，它显示了错误的位置。

当我在Google地图中检查该邮政编码时，它可以正常显示；因此，经纬度没有问题。相反，还有其他一些我无法找到的东西。

请帮我。我尝试搜索并使用许多不同的编码方式，但是仍然保持不变。

这是我的JS代码，其中我计算了多个距离。

并且请注意，此邮政编码问题仅在一些特定的邮政编码中发生：
