Background of the issue:
I am trying to translate a custom post type (CPT) 'author' into Croatian using WPML with the 'Translatable (use translation if available or fallback to default language)' option. The original slug is 'author', and I'm translating it to 'autor'. The CPT is registered with a plugin, and here is the code for that: hidden link. I am using WPML plugins and the Twenty Twenty-One theme with no modifications. I have another ticket open which is not related to this: https://wpml.org/forums/topic/translate-cpt-slug/. The issue can be seen here: hidden link
Symptoms:
The permalink for the Croatian version of the post is 'hidden link' instead of 'hidden link'. The word 'author' is not translated to 'autor', although the language switcher in the footer uses the correct link.
Questions:
Why is the slug 'author' not translating to 'autor' in the permalink?
How can I ensure the translated slug appears correctly in the permalink?
