Hi,
I believe the links might be incorrect, as they point to the live site. The results you see there are elementor templates, that’s because it’s selected as a post type to return, make sure it’s not selected here.
What I noticed on the staging is that the index table was not enabled, so I configured it and enabled it for you. The index table picks up keywords from post contents, which may not be visible in the database.
After that I’m seeing very similar results for all languages. For example zamorano in english, zamorano in spanish.
I believe this is the correct configuration.
