Farmer villagers always trade a night vision suspicious stew or suspicious stew with a data value of 0. In the code of the "\trading\economy_trades\famer_trades.json" on line 244 it says '"item": "minecraft:suscpicious_stew:0"' this ":0" at the end prevents the "random_aux_value" function from randomizing the type of stew. By removing the ":0" the issue will be resolved. I believe this is a mistake because then why have the "random_aux_value" function in the code for the trade? My friend and I made an addon removing the ":0", which fixed the issue.
