Farmer Villagers don't accept pumpkins

If I am trying to trade with farmer-villagers, they don't accept any pumpkins it happens very often I also try to relog into the world, but it doesn't help.

Steps to Reproduce:

1. Place 6 or more pumpkins while facing east, west, or south
2. Break and pick up the pumpkins
3. Try to trade the pumpkins with a farmer villager

Another way to reproduce:

1. Use the /give command to give yourself 6 pumpkins with a data value of 1 or higher
