Same problem here! Need to talk with WPML team?
In my case calling to field and forcing original post no solved the problem:
USING THIS
$id = icl_object_id($v['wp']->ID, 'property', true, ICL_LANGUAGE_CODE);
$img = get_field('galeria',$id);
AND THIS
$id = icl_object_id($v['wp']->ID, 'property', true, "en");
$img = get_field('galeria',$id);
OR THIS
$id = icl_object_id($v['wp']->ID, 'property', true, "es");
$img = get_field('galeria',$id);
In this 3 cases, order is correct in main language (es) and incorrect in others.
