Problem:
If you're trying to translate an ACF custom post type using the WPML Translation Editor and notice that all fields except for the title are empty in the English translation, it might be due to the need for additional configuration.
Solution:
We recommend installing the "Advanced Custom Fields Multilingual" addon to enable the translation of ACF Fields and Post Types with the WPML Translation Editor. You can find this addon under Plugins > Add new > Commercial or directly at https://wpml.org/download/acfml/?section=changelog (please use version Version 2.1.4.2).

After installation, ensure that all field groups that include fields translated with the WPML Translation Editor are set to "Same fields across languages". Additionally, edit your CPT in ACF and save it again to make the CPT available at WPML > Translation Management for translation. For more guidance, visit https://wpml.org/documentation/related-projects/translate-sites-built-with-acf/.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If you still need assistance, please open a new support ticket at WPML support forum.
