Hi @eaglejohn
I believe the plugin author has added some compatibilities with WPML so they should have a better compatibility. The fact that the field is translated without error shows it.
The issue you have is weird, though. Could you please check the entries in the database for both master and translated posts? You can check the custom field in the “wp_postmeta” table.
Also, could you please check this page: https://www.advancedcustomfields.com/resources/multilingual-custom-fields/?
Thanks!
