Old Products, can't select newly translated categories

Hi, good day !

I’m currently facing a strange issue, and I believe this issue may come from Woocommerce as it is the main plugin used .

Website : http://www.hooki.pro

Basically, I have a multi-language website using Polylang + Woocommerce . Everything works fine according to my needs : I need the shop to be in english only, while keeping a “translated environment” (category name, menu, and so on).

Everything works fine, except for this small issue : I finished my shop, installed the language and added tranlation for categories. For products added AFTER I installed the languages, no problem : I can easily select the category for all 3 languages I have, and it’ll show up.

However , for products that were added BEFORE I installed the language, the translated categories simply don’t show up at all !

Some practical example :

The only products that show up in this category is the one that I added after I installed languages : http://www.hooki.pro/product-category/%D1%81%D0%BF%D0%B5%D1%86%D0%B8%D0%B0%D0%BB%D1%8C%D0%BD%D1%8B%D0%B5-%D0%BF%D1%80%D0%BE%D0%B4%D1%83%D0%BA%D1%82%D1%8B/

Installing & Deinstalling woocommerce doesn’t change anything. So .. the only way I see right now would be to duplicate the products and remove the old ones (didn’t try it yet but anyways it seems quite time consuming)

I added some screenshots for references : http://postimg.org/image/qxetxvrif/

Any help would relly be helpful, a way to make it so i’d be able to select language specific categories for all products, not only new ones.

I’m using polylang to manage the translation.

Thanks in advance !
