Reported for: WPML Multilingual CMS 4.5.7
Overview of the issue
If you are using some page builders, such as those used by Divi or Flatsome themes, you will notice that if you open the original page and update it, even without adding any change, the translation is overwritten in the front-end with the original content.
However, when you open our Classic or Advanced Translation Editor, the translations are still there. Once you save them, the translations appear again on the frontend.
Workaround
Our developers are working on it. In the meantime as workaround, you can install the Classic Editor plugin.
Alternatively, you can add the following constant in your wp-config.php file:
define( 'WPML_TRANSLATION_AUTO_UPDATE_ENABLED', false );
