Villagers Breeding non-usable Brown Coats

Created a test world to see how old features are interacting with the new and the "Infinite Village Breeder" is working but it is only Breeding Brown Coat Villagers with the old skin and no trades. Not sure if this is a Bug or intended. The Image Attached shows all the villagers bred are Brown coats. I used the glass blocks to represent the three villagers that I spawned in using the Spawn Egg. Let me know if you need anymore information
