[Resuelto] Translation on the frontend is correct, but not in the backend

Background of the issue:
I am using the WPML plugin to translate a post on my WordPress site, enlace oculto. I am not following any specific documentation, just performing normal activities related to post translation.

Symptoms:
The translation appears correctly on the frontend of the website, but it does not reflect accurately in the backend.

Questions:
Why is the translation correct on the frontend but not in the backend of my site?
How can I ensure that the backend translation matches the frontend?
