Hello,

Building on the previous solution with a more generic one, dropping this in our functions.php file fixed all galleries on the site:

add_filter( 'acf/format_value/type=gallery', 'fix_gallery_order', 100, 3 );
function fix_gallery_order($value, $post_id, $field){
    $order = get_field($field['name'], $post_id, false);

    if(is_array($order)){
        $order = array_map(function($id){
            return apply_filters('wpml_object_id', $id, 'attachment', true);
        }, $order);

        usort($value, function($a, $b) use ($order){
            return array_search($a['ID'], $order) - array_search($b['ID'], $order);
        });
    }

    return $value;
}
