Hi Christopher: Sometimes the counter bearing area or duplex has unhappy string length combinations. This aliquot area may be out of tune with the speaking length to such a degree that you hear a very fast beat or buzz. You might try putting a drop of glue on this segment of the string. This will change the frequency but not damp the string nearly so much as touching it with your finger. See if you can find the right combination. If you have read Ed McMorrows book, you will know how he deals with this in changing the counterbearing height and making a smaller radius V-bar contact with the string.
