Background of the issue:
I am trying to translate CTX Feed Pro's Category Mapping UI into French using WPML. I have followed the necessary steps, including enabling taxonomy translation, translating every term, synchronizing assignments, clearing caches, and verifying plugin versions. Despite these efforts, the translated categories do not appear in the CTX Feed's Category Mapping dropdown when the WPML admin bar is switched to French.

Symptoms:
When I switch the WPML admin bar to French and open CTX Feed → Category Mapping → Add New Mapping, the dropdown is blank—no French categories appear.
Questions:
Does WPML’s 'use translation if available or fallback' setting populate taxonomy dropdowns in the admin, or only on the front-end?
Why are translated product_cat terms not being registered in the French admin context for third-party tools like CTX Feed?
Should I enable 'Adjust IDs for multilingual functionality' under WPML → Languages to expose fallback terms in admin dropdowns?
Are there hooks or filters needed to allow CTX Feed to retrieve WPML’s translated term list in the backend?
I confirm that the CTX Feed Pro plugin is officially compatible with WPML. https://wpml.org/plugin/ctx-feed-pro/
There is a good guide that WebAppick created here.

Have you followed these guides?
(You mentioned another guide.)
You mentioned that you want to translate the plugin's UI. For this, you need to scan the plugin for strings in WPML -> Theme and plugins localization, and translate the strings in WPML -> Strings Translation. Please read more about it here.
