Problem with attribute import?

Question

WooCommerce

The problem in general is that I don’t understand how to correctly import an attribute whose value is passed in the form (45 | 46 | 47 | 48 | 49 | 50), after which the product is somehow tied to taxonomy, that is, it saves the parameters there somewhere. After import, I always get the first value (45) there are no others, for taxonomy there must be some other separator or what?

(I use Wp ALL IMPORT)
