Combination Import/Update from CSV bug?

[Neo9686]

Hello, we are running Prestashop 1.7.8.8 on our website and we use the Prestashop's native CSV import module for products and combinations. The system seems pretty solid but something is not quite right when it comes to update existing combinations.

Regarding simple products (no combinations) we use to upload a file that contains just the minimum amount of informations (Product ID/Reference) and the field that we need to update/change, like the price or the EAN number for example. This seems to work perfectly with simple products, but it does not with combinations: if we want to do the same with combination we must specify the product ID/reference, attribute and attribute value so that the system can identify the single combinations and update the correct one without error. But that's not the case because if we choose to update a single field we'll end up with all the combination's field empty, except for the one you chose to update.

That's a pretty major issue, did it happen to anyone other then us? Thank you in advance.
