Problems with excluding posts with password protection

Hi! Im trying to exclude password protected posts from the ajax load loop. i have hadded custom_args=”has_password:false” to my shortcode, but this does not work correctly. It should hide all the password protected posts from the loop, but insted it shows only the password protected posts. Am i doing somthing wrong?
