Hi Mindofmedia,
I’ve found the solution. If you go to “edit a product” you can set for every product attribute if it should be translated or not. So for the Dante theme you have to set the attributes sf_product_short_description and sf_product_description from “do nothing” to “translate” in the edit product screen.
You can now translate the product description in Woocommerce Multilingual->products
Hope this works for you as well.
