Put the summary of the bug you're having here

What I expected to happen was...:
When trading with one of my farmer villagers, I noticed while all the other trades were decreasing in price, the pumpkin trade was increasing (in Java). While trading with villagers, in my experience villagers usually (in Java) either raise all of their prices or lower all of their prices. If you trade with them their prices lower, if you hit one of them, their prices raise. I don't remember Java being like bedrock with the whole supply and demand thing.

What actually happened was...:
Without harming the villager, I traded with it using melons and pumpkins and just like normal all of his trades lowered, except the pumpkin trade, which raised from 6 to 7, then to 11.
