When I try to make a librarian spawn egg, something went weird. I spawned farmers, clerics and other villagers with white cloth，unlike
/summon villager ~ ~ ~ {Profession:1}Steps to reproduce
1. Make a librarian spawn egg.
/give @p spawn_egg 1 0 {EntityTag:{id:"villager",Profession:1}}2. Spawn some villagers use the spawn egg in step 1.
3. Trade with them.(not all villagers)
This works as intended. The
Carrierproperty is needed as well to define which trades the villager has.
