So, like many players I decided to build a villager breeder. After breeding a villager, I decided to let a zombie kill him and cure him after. Once I cured him, he seemed to change what type of villager he was. Previously a Savana villager, switched to a default plains villager. He did not have any of the discounts that should of been present. I decided to cure him again. Again he didn't receive a discount after curing. This is taking place on realms, on the newest version of Minecraft Bedrock WIN10. 

EDIT: After trading with him to lock his trade, I broke his workstation and he immediately lost his job. So it could be that villagers from a breeder are buggy.
