Some Librarians are trading an “Enchanted Book” with no associated enchantment. These Librarians used to trade normal Enchanted Books with enchantments for the same cost as they currently do, and in the same slot in their trades list. The only difference is that the actual enchantment is removed. These villagers had been locked into their trades since before the bug appeared. The enchantmentless Enchanted Book is available for valid trade with emeralds and a normal Book. This bug is not universal to all villagers in the save file. It only has affected certain Enchanted Books in certain Librarians. Some Librarians have lost all their enchantments, while others have only lost one or two, but maintained the rest. And some villagers were not affected at all.
