I have placed some tiered beehives, and a nitwit will not recognise that

I'm using resourcefulbees-1.16.5-0.5.10b.jar

Nitwit villagers wear robes that are green on top. They cannot acquire a profession, trade, or gather around bells, but are still able to breed. They are not equipped with a level stone since they cannot trade.
