"Log in" Link Doesn't Go to Login

I’ve set this up on another site and I don’t have this issue. But on a fresh new install if you select “Register” or “Lost your password?” the “Log in” link goes to the same page that you’re currently on.

Say for example you select “Register”. It takes you to the registration part, but the “Login in” link goes back to:

?action=register
http://example.com/login/?action=register

When is should just go back to:
http://example.com/login/
