EM 5 to 6 workaround fix for Name returning "Array Array"

function my_em_get_name( $name, $EM_Person ){
  $first_name = ( is_array($EM_Person->first_name) ) ? $EM_Person->first_name[0]:$EM_Person->first_name;
  $last_name  = ( is_array($EM_Person->last_name) ) ? $EM_Person->last_name[0]:$EM_Person->last_name;
  $fullname   = $first_name.' '.$last_name;
  $name       = wp_kses_data(trim($fullname));
  return $name;
}
add_filter('em_person_get_name','my_em_get_name', 100, 2);
