V8x product type - standard product switch to product with combination

[rayban]

Hello, I have products with attributes. All products have attributes.

When I import products that previously had attributes, the product type settings go lost, and all products are displayed as Standard Products after the import. This hides the attributes, and importing the attributes is no possible.


in database the field product_type is empty after import: jzry5_product / product_type


How can I change all products in the batch to Product with Combination?


THANK YOU!
