MyCurriki tab pages don't re-direct when logged out

When logged out, the "Profile" tab is the only one that re-directs to the login page - the others show the following as the page title / user's name:

"$userobj.first_name $userobj.last_name"

Example: http://current.dev.curriki.org/xwiki/bin/view/MyCurriki/Blog (when not logged in)
