Hey elliot,
hope everything is good. 🙂
Solved it by remove the standard custom fields from wordpress, looks like they doubled the values by saving them seperatly.
// remove non ACF custom fields
function remove_custom_meta_boxes() {
remove_meta_box('postcustom','post','normal');
remove_meta_box('postcustom','page','normal');
}
add_action('admin_menu','remove_custom_meta_boxes');
Thanks for all your work elliot, most valueable plugin ever. 🙂
