Problem: If you have set your site to display untranslated items in alternate languages and have done the same for taxonomy terms, you might encounter an issue where, after translating a taxonomy term, it fails to pull in associated post items that are not translated into the alternate language and are assigned to the translated taxonomy term.
Solution: We recommend checking the following documentation on how to display untranslated taxonomy values as a fallback:
It is important to note that if you have the 'Translatable - use translation if available or fallback to default language' setting enabled for any post type, all posts belonging to those post types will be associated with the default language taxonomies. This means that if you translate the taxonomies, there will be no posts associated with them in the secondary language unless you change the settings for your items to 'Duplicate'.
If this solution does not seem relevant to your situation, please do not hesitate to open a new support ticket with us here.
