Crafting recipes with 'IngredientsLeftover' consumes all items in SHIFT holding

Setup:

Minecraft: 1.21
Paper: 1.21-130-master@b1b5d4c
MM: MythicMobs-5.8.0
MC: MythicCrucible-2.2.0-SNAPSHOT (Latest downloaded Build 3995 from 23.04.25)

Here is an issue that if you have crafting like this:

WheatFlour:
  Id: wheat
  Display: '<green>Wheat Flour'
  Recipes:
    SHAPED:
      Type: SHAPED
      Amount: 1
      IngredientsLeftover:
        - air | air | air
        - air | MortarAndPestle | air
        - air | air | air
      Ingredients:
        - wheat | wheat | wheat
        - wheat | MortarAndPestle | wheat
        - wheat | wheat | wheat

If you press SHIFT and try to craft a lot of WheatFlour with SHIFT - MortarAndPestle will be consumed with first craft and if you're not in creative. If you in Creative - all items will be dropped to the inventory. MortarAndPestle - is also the MM item. If we are using only one crafting recipe - MortarAndPestle moves to the top left corner, instead of center.

If to add something like this:

      IngredientsLeftover:
        - air | air | air
        - air | MortarAndPestle | air
        - air | bucket | air

After crafting we will have both IngredientsLeftover ingridients in the left top and left middle positions like this:

        - MortarAndPestle | air | air
        - bucket          | air | air
        - air | air| air

Feel free to ask logs or screenshots or more detailed info.

Thank you!
