This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing an issue with their multilingual WooCommerce site where some taxonomies are forced to be untranslatable, causing problems on their website.
Solution:
If you're facing a similar issue, we recommend trying the following steps:
1) Navigate to WPML > Settings > Taxonomy translation and ensure all related product taxonomies are set to 'Translatable - only show translated items' or 'Translatable - use translation if available or fallback to default language'. For instance, 'product_cat' (Product category) and 'product_tag' (Product tag) should be translatable.
2) Alternatively, you can override theme XML rules for specific taxonomies by checking the theme XML file in the theme root folder and changing 0 to 1 (translatable).
3) Another option is to go to the WPML -> Settings page and click the Custom XML Configuration tab. Add the taxonomy rules as per our documentation. Please see the following for details:

We highly recommend using method #1, which is straightforward and does not interfere with the theme's default configurations.

Hi,

Thank you for contacting the support.

This happens when some taxonomies which are offered by other plugins or theme, are set to not translatable in their configurations (usually via a theme XML file in the root folder).

You can override this by any of the following methods:

1) Go to WPML > Settings > Taxonomy translation and make sure all the related product taxonomies are set to (click on the lock to unlock) 'Translatable - only show translated items' or 'Translatable - use translation if available if available or fallback to default language'. For example, product_cat (Product category) and 'product_tag' (Product tag) should be translatable.

2) Override any of theme XML rules for specific taxonomies by checking theme XML file in the theme root folder and change 0 to 1 (translatable).

3) Or go to the WPML -> Settings page and click the Custom XML Configuration tab. Add the taxonomy rules as per our documentation. Please see following for details:
- https://wpml.org/documentation/support/language-configuration-files/
- https://wpml.org/documentation/support/language-configuration-files/register-custom-terms-types-taxonomies-as-translatable/

I'll, however, recommend using method #1, which is easy and does not interfere with theme's default configurations.

Regards.
