Problem:
You are trying to save translations for an ACF options page and expect to see translations on both the backend and frontend. However, the translation appears on the frontend, but the backend options page still shows untranslated content. Additionally, if the options page is saved a second time, the frontend also reverts to untranslated content.
Solution:
We recommend checking the translation option selected for your options page. The available options are:

• Same fields across languages
• Different fields across languages
• Expert

Please adjust the Multilingual Setup in your ACF -> Field Groups settings accordingly. In this case, you can switch to the Expert mode and set the fields in question to Copy Once. Please review our ACF guides and one known issue.

If the issue persists, it might be due to an outdated solution or a different problem not covered here. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
