Hide Backend not hiding wp-login

Hi,
on the last project I have a problem with the hide backend feature. wp-admin is secured and hidden, but not wp-login. When I type http://www.mysite.com/wp-login it still works, when I try http://www.mysite.com/wp-admin I got the error page.
Any ideas how to solve the problem? Maybe it could be some incompatibility with WPML or is it a small bug in iThemes Security?

Thx
Rob
