Why Google is not indexing each country/language subfolder on the ranks?

[administratorwibee]

Hi folks,

We use Magento 2 for the multi-country shops (its a multistore). The URL: www.avarcas.com

The first days Google indexed the proper url in each country:

• avarcas.com/uk
• avarcas.com/de
• ...

Some days later, all the countries are just indexing / (the root).

I correctly set the subfolders in Webmaster tools.

What's happening?

Thanks
