[Cerrado] Permalink/slug of custom post type is being translated, causing 404 errors.

Background of the issue:
I am trying to prevent WPML from translating the slug/permalink of a custom post type called 'Students' on my site enlace oculto. The slug translation setting is disabled, but the issue persists.

Symptoms:
WPML is translating the slug/permalink of a custom post type, causing 404 errors because the pages don't exist under that post type.

Questions:
Why is WPML translating the slug of my custom post type even though the translation setting is disabled?
How can I stop WPML from causing 404 errors by translating slugs?
