Problem solved. I modified the file main.php from Magic Fields 2 plugin root directory.

// Check if the post has a special template
  $template = get_post_meta($post->ID, '_wp_mf_page_template', true);

  if (!$template || $template == 'default') {
    return;
  }

  $template = TEMPLATEPATH.'/'.$template;
   if (is_search()) {
    return;
  }

  if ( $template = apply_filters( 'template_include', $template ) ) {
    include($template);
    die();
  }
  return;
}
