How to import combinations in different languages

[MKZ Industries]

Hi all, 

I am using Prestashop 1.7.8.8.

I have my shop configured in 2 languages, Spanish and English, and while I have no problems importing products and categories for both languages, I cannot do the same with combinations.

For example, I have a product with 3 available sizes, small, medium and large. I am trying to upload 2 different .CSV with these combinations for both languages, selecting in the import configuration menu the corresponding one for each file. Both files are the same (ID, reference, price impact...) but for the "Attribute" and "Value" columns that are as follow for each language:

 

SPANISH / ENGLISH

"Tamaño:select:0"; "Pequeño:0" / "Size:select:0"; "Small:0"
"Tamaño:select:0"; "Mediano:1" / "Size:select:0"; "Medium:1"
"Tamaño:select:0"; "Grande:2" / "Size:select:0"; "Large:2"

 

Why this is not working? Is this a common issue with Prestashop import feature? Is this solved in Prestashop 8?

So far, I have solved this by translating the names one by one at the "Attributes and Characteristics" menu after importing them in Spanish, but the amount of combinations is increasing quickly and I would like to have a method to do it automatically. 

Thanks a lot in advance for any help on this, it is driving me mad. 

Best regards, 
Xabi
