You can figure out that this is probably wrong even without knowing Japanese. It's implied the promotion ceremony always happens in April each year (this is probably a major reason for the time skip between Auction arc and Rose arc). Any promotion at any other point in time is an exception and the promoted investigator must have done a major feat. Killing Noro, while certainly a major success, is just not big enough to warrant such a special promotion.

My advice: Be sceptical of any rank changes if no promotion ceremony took place in the mean-time (i.e., if we didn't enter the month of April yet since the latest previous statement of an investigator's rank).
