<p>If my son or daughter came to me with that concern I would advise him or her to email the admissions counselor with the information. I would not be overly aplogetic or flowery in your email, just give the information in a declarative fashion. I think it shows that you are very concerned about your integrity (which is a good thing). Also note that your recommender gave you the letter. I don’t think its an overwhelmingly big deal, but sending the clarificaition shows that you pay attention to detail and that your are very serious about Stanford.</p>
