Villagers won't accept a new workbench after being cured

After curing a zombie villager, they won't accept a new workbench. They only stick to their old workbench and if you break it to move it, they won't take it. I spent a week working on a trading hall, a breeder, and a zombie curing thing, and this bug ruined all my work. Because they won't accept a workbench when I move them to my trading hall, they can't replenish their trades. I now have to either redesign and rebuild my entire system or I am stuck with uncured villagers with really high prices. Please fix this bug.
