Using WPML Booster

Hi,

I am translating my website with WPML and I am looking to translate and use Booster with my translated website. I have activated Booster WPML but I don’t understand how to use it.

For example, on a certain product category, the button changes text. This is not reflected on the translated products and I can’t get the translated categories to have a different button.
The same goes for the different fields added on the product pages.
Can you help me?

Example of the original page in French:
https://www.chassitech.com/produit/chassis-flottant-en-bois/
Its translation in English:
https://www.chassitech.com/en/product/wooden-floating-stretchers/

Thanks
