[Resuelto] Post translation uses WP Editor instead of Translation Editor

Background of the issue:
I'm trying to translate a post on our website, but it keeps showing the original Dutch content. It seems the page loads the WordPress editor content of the translation and not the translations we entered in the Translation Editor. I made a short video showing the issue: enlace oculto

Symptoms:
The translated content from the translation editor is not displayed. Instead, the Dutch content appears in the translated WP Editor page.

Questions:
Why is the translated content from the Translation Editor not displaying?
How can I ensure the translated content appears instead of the original Dutch content?
