Protected content

I'm using this module to deliver a mobi version of selected content on a subscription-based site.

Some content is free for all users, other content requires a user with a certain role (I'm using the node access module to determine which content types to restrict).

On my mobi site, if an anonymous user tries to view restricted content, they see the log in box (as planned). However, then there's a second log in block, and actual content shows up underneath both blocks.

To test, use: http://www.operamini.com/demo/
and hit cookpolitical.hfwebdev.com

Any thoughts on why this is happening? Is it related to the module or have I set things up incorrectly?
