Ink sacs traded from a wandering traders wont trade back to librarian

I traded 1 emerald for 3 ink sacs from a wandering trader and my librarian villager buys 1 ink sac for a 1 to 1 ink sac to emerald trade but the ink sacs i got from the wandering trader wont trade in the librarian, don't know if this is an nbt problem not being tagged correctly or if this is an intended mechanic to stop from cheating the villager trades
