before your ticket is assigned to one of my colleagues, please allow me to walk you through some initial debugging steps. This will help speed up the support process.
I suppose you wish to disable some specific custom fields from being translated
The problem is LABEL of custom field. Not all field itself. I found the solution to add this code in wp-config.php:
define( 'ACFML_EXCLUDE_FIELD_GROUP_STRINGS_IN_POST_JOBS', true );
