Good afternoon.
There is an infoblock with properties: list, date, string, number.
When importing products from a csv file, all property values ​​except for the "list" type are filled in correctly.
The list property field is left blank. How to force to enter values ​​from a file when importing?

Moreover, if you manually enter the correct property and export to a csv file, then it is written there in the same way as in the case of import.
There are more than 10k positions, it will not work to kill manually.
