How to remove duplicate titles on wp-login.php and post

How is this possible to have duplicate title tags on the login? Where would google get this from? There are actually two items and I need help to get rid of both of them please. The blockquotes below is what google tells me when I downloaded the error table.

This first one is frustrating because I posted article and then updated it right away but somehow google sees both of the URL’s and one does not even exist anymore.

Pages with duplicate title tags

http://surfinjaco.com/2008/12/kelly-slater-says-terrorism-overrated/ http://surfinjaco.com/2008/12/kelly-slater-says-terrorismis-overrated/

The second link is the incorrect one is not on the site any longer. How can I get rid of this?

The second one issue is the wp-login.php duplicate issue???
