In smoker only recipes for items i have in inventory are shown. Switching to "Showing all" does not work. If I remove a Item from my Inventory, the recipe will be removed as well in both categories.
If I have all recipes before I firstly lock inside the Smoker I can't remove the recipes I can't make by switching.
Only the Button is switching and not the shown recipes.

I have tested it in creative, survival and adventure. The recipes were unlocked by command.
