When a multilanguage feed is being imported, the taxonomies (in this CarDealer theme case; Car Producers) are not created for each language. They are only created in Dutch (our primary language) and then for each subsequent language the import is assigning the cars to Dutch Producer Taxonomy.
Resulting in no Producers in other languages, and the Dutch Producers having a total of x4 (because each of our 4 languages are imported in Dutch, so the Cars count in the producers shows 4 instead of just 1 (in case of a single car)).
Expected behavior: If taxonomy is not present in import Language, create it. And then import the car in the correct taxonomy language.
