I’ve found the issue in case i had the same problem you have to set nothing as static page and it’ll work in separete page.
OK I found the issue, as your test site have lots of plugin, and they pushed my page rewrite rule to bottom. You can check it here: http://www.pigomultimedia.com/testing_area/beta_site_9ZH/wp-admin/tools.php?page=rewrite-rules-inspector I will find a way to fix this issue asap, but I am sure if you use in general site it will work as usual.
