Emails match. I just looked at my GitHub profile to confirm and signed the
CLA again. Is there anything else that I should check?

Most of these title attributes are unnecessarily redundant. The only time they are useful is when the link text doesn't describe what the link will do (like "click here" or "http://localhost/"), or if it opens in a new window.
