WooCommerce product attributes are not imported

We have bought the plugin and have tried to import with the csv importer the exported shopify csv file. The import itself looks good, all products are there and with all the images. Also it created variants. However, if you look closer then the variants are not correctly imported – it means that each of the variant product is not correctly set with the variant value – in the following case it is written “Any Farbe” (translated “color”) – instead of setting the correct color

Expected: that each of the variant product has the correct attribute-variant is set.

Also if look into the attributes page, the attribute “Farbe” is not created.

It would mean a lot of work if we need to set all the product variants correctly with the correct attributes.

Thanks
