Is another entry moved up if a Category Winner withdraws or is disqualified?
Yes. Category Winners are determined in July. Category Winners are not announced at that time. If an entrant withdraws, and they happen to be a Category Winner (although they would not know this), the next highest scoring entry in that category is moved up to become Category Winner. However, another entry would not move up to fill the vacant spot as a Category Finalist because the Final Round judging would have already been completed.
