Villager trading hall

First villager trading hall of the world. Never traded with the villagers before. 

They are not losing their job when their work stations are destroyed. I made sure everything was fine. The bed is connected and everything. But the villagers are not losing their jobs, no matter how many times i destroy the work stations.

I waited after destroyed, placed them again. Didn't work. I tried the boat suffocation method, tht didn't work as well.
