(1) In each case where a returned ballot (other than those returned by the post office as undeliverable) is not validated for counting, whether because the signature cannot be verified, because of failure to verify address by elector, a procedural mistake has been made by the elector, or some other reason, the election administrator shall enter in a log he maintains for that purpose, the following information:
(a) the name of the elector involved;
(b) the nature of the item in question;
(c) the date, time, and manner by which notice to the elector was given or attempted; and
(d) the final resolution of the question and the manner in which it was resolved.
