1.12.2 Problem with a shapeless recipe and Ore Dictionary

I have an item which takes durability damage in the crafting table after each crafting.  I have it registered in the ore dictionary using the WILDCARD_VALUE. When I use the item in a shaped recipe, the item takes durability damage and is reusable just as it's supposed to be. But if I make a shapeless recipe, it becomes completely useless after only being used once.  Can someone help me figure out where I goofed up with this? Thank you.

The item class:

public class ItemMortarAndPestle extends Item {

	private Item containerItem;

	public ItemMortarAndPestle(String name) {

		setUnlocalizedName(name);
		setRegistryName(name);
		setMaxStackSize(1);
		setMaxDamage(64);
		setNoRepair();
	}

	@Override
	public boolean hasContainerItem() {
		return true;
	}
	
	 @Override
	public ItemStack getContainerItem(ItemStack itemStack) {
		return itemStack.getItemDamage() < itemStack.getMaxDamage() ? new ItemStack(itemStack.getItem(), 1, itemStack.getItemDamage() + 1) : ItemStack.EMPTY;  
	}
}

 The item's Ore Dictionary registry entry:
 

	OreDictionary.registerOre("mortar_and_pestle", new ItemStack(ItemInit.mortar_n_pestle, 1, OreDictionary.WILDCARD_VALUE));

And lastly, an example of a shapeless recipe in which the item is used:  (This example stops working after one use)

{ 
  "type": "minecraft:crafting_shapeless",
  "ingredients": [
    {
	  "item": "maidensmaterials:amethyst_chunk"
	},
	
	{
	  "type": "forge:ore_dict",
			"ore": "mortar_and_pestle"
	}
  ],
  "result": {
    "item": "maidensmaterials:amethyst_fragments",
    "count": 8
  }
}
