Year Make Model Search for WooCommerce

● WooCommerce 7.2.2
● PHP7.4.33
● MySQL5.7

I am creating a new website. When I “export sample CSV” and then “import CSV” without processing the data, an error occurred and the csv could not be imported. The contents of the error are as follows.

[Row #1 was not imported. The product with SKU or ID “xxx” does not exist.]

[Row #2 was not imported. The product with SKU or ID “xxx” does not exist.]

I would like to know if there is a possible cause or solution.

Thank you
