Prestashop overwrite some data not present in the Combinations CSV file, maybe a bug?

[ballashop]

Hi,

I downloaded the csv file of the combinations to perform some tests.

combinations_import.csv combinations_import.csv

I modified the file in order to test an existing product in the PS demo.

import with only reference.csv import with only reference.csv

The goal is to modify the following product which has 3 combinations:

The import is done without any problems, but once the data was uploaded I realized that PS overwrote some unsolicited fields such as quantity and price impact. These fields were ignored during loading but PS has still performed a sort of reset of them.

Before the import the 3 combinations had the following data:

After the import, the data were reset:

how can i import some data without modifying the other data not included in the csv file?

Thanks for any reply.
