I noticed this last week in the 24w18a snapshot and also in the 24w19b this week. I also went back a couple of snapshots and it works fine. it seems to have popped up in 24w18a.

it seems to do this also for the copper trap door and the copper door.

Steps to reproduce:

1. make and load a world

2. get 2 crafters 

3. put in the first crafter the recipe for iron bars or iron doors

4. put in the 2nd crafter the other recipe 

5. then the second crafter is stuck on the first recipe 

I started a brand new world and it still does this.
