I had some pumpkin in my inventory and when I went to trade with a farmer villager, the trade was marked unavailable by the villager citing the item wasn't in my inventory.
The problem can be solved by simply placing one of the pumpkin and breaking it.
It's a user created village if relevant.
How were the pumpkins originally obtained, and in approximately what Minecraft version?
If you place and break just one of the pumpkins, does it then stack with the others as before?
