Librarian name tag price doesn't reflect the new crafting recipe

The Librarian has a name tag trade on master level, but its cost still reflects it being a rare non-craftable item, even though it is now craftable very cheaply. Crafting a name tag is currently (extremely) more cheap than trading its ingredients for emeralds and buying a name tag. (500~paper = 20 emeralds, and 720~iron nuggets turned into ingots=20 emeralds, whereas one of each is 1 name tag)

Steps to reproduce:

Spawn villagers, give them a lectern work station and level them up to master until you get a name tag trade.

Result:

Name tag trade costs 20 or so emeralds.

Expected result:

Name tag reflects new cheap crafting recipe and has a new price for 1 emerald.
