WooCommerce Language localization issue

Hello! I have an issue with language of the WooCommerce plugin.

My website is in Italian, so, even if I set the WordPress language in Italian, the WooCommerce localization with functions such as “Add To Cart” or “Select Options” still appear written in English.

This happened during an update, and I tried all that I could to set it again to Italian, without success. Could you please tell me what happened and if there’s a workaround? Thanks in advance, and wish you a happy new year!
