Resolved conflict between ID and SKU

Hello, something happened during the product import from Virtuemart. After the import, when I create a product variant, the variant inherits the data from another product that is not the parent product. The variant inherits the data from the product that has the same SKU as the variant's ID. For example, the created variant has ID 1594, and it inherits the data from the product with SKU 1594.

what could have happened? Something in the structure isn't right.

I'm waiting for help.

Thank you.
