[Closed] I can't translate WooCommerce Categories Meta title and description

I can't translate WooCommerce Categories Meta titles and descriptions anymore.
I used to translate them individually through Products > Categories > [select language from language menu] > [Edit categories one by one] to adjust the Meta title and description values. But these don't apply on frontend anymore, even after updating the category individual page settings.

I read this ticket carefully: https://wpml.org/forums/topic/wrong-yoast-meta-language-on-translated-woocommerce-category-pages/

First, I think the terms used in this ticket/solution are not accurate/don't correspond to the actual terms used in WPML admin, so that I'mo not sure where I should look. So I test two different methods.
"If you're experiencing this issue, it's important to note that from WPML SEO 2.2.0 onwards, term meta such as SEO titles and meta descriptions for categories can be translated via WPML → Translation Dashboard as String Packages."

There are no such "String Packages" section under Translation Dashboard.

So 2 options:
1. You guys meant to translate these Meta terms under WPML > String Translation > Find the corresponding meta title and description entries and translate them here.
> I updated the original value from the category page to force the update, for something veryy specific. Then I search in String translation for that very specific Meta title, which I could detect as yoast-seo-term-meta / Name: :product_cat-269-wpseo_title, made sure it's the right original Value, and translate it to french. Then I checked the french pages: this value hasn't update in the individual french category edition nor on the frontend french category page

2. You rather meant to go through Translation Dashboard > Yoast SEO > Term Meta > Check Term Meta > Translate > Then go to the Translation panel, where then ALL the meta titles and description appear.
> I added me as translator for french Met terms, then went to the Translation panel, where was offered to translate this content. So I translated every single existing category meta title, meta description and focus keyword with something specific, to reach 100%, then hit Save.
Then I checked the french pages again : these values still havn't updated in the individual french category edition nor on the frontend french category page.

In short, I tested 3 different methods to translate this content. I even cleared the WPML cache (while disabled in local env).
None of these method helped getting my meta title and description translated.

I don't use any cache plugin under this environment, where all other translation updates reflect reliably.
