API Return Error on language categories?

Hi All.
If you call the product through the API by setting the language to Italian, the categories return in English and in some cases completely incorrect.

https://world.openfoodfacts.net/api/v2/product/8000500415573?cc=it&lc=it&tags_lc=it&fields=product_name%2Ccategories%2C%2Cbrands%2Cimage_front_thumb_url%2Cimage_front_thumb_url%2Cimage_front_url%2Cimage_ingredients_url%2Cimage_url

if you search on the site, the categories are language correct.

Where i wrong ?
