If the honey isn’t being capped off my suggestion is to reduce the rate of increase in supers. The bees will fill then cap the honey efficiently if there is less space to move into. A common trap I see is too many supers/frames being added too quickly which provides too much space, resulting in the collected nectar/honey being spread over too much area and never being capped. This becomes an issue for extraction as there will be a large amount of unripe honey in the hive which the bees may not manage to cap before the season’s end.
