Villagers not resocking or leveling up

My villagers are not restocking or leveling up after being zombified and cured.

Steps that reliably recreate the issue:
Give villager workstation

Trade with villager

Zombify and cure x3

Trade with villager again
Does not restock or level up

Tried:
Breaking and replacing workstation: Produces green particles but does not restock or level up after several in game days
