[1.16.5] Help with Creating a Custom Recipe Type

I made a crafting table block that behaves like a crafting table but only my custom recipes work on it. I made a container, recipe, recipe type, and serializer for it but my custom recipe doesnt work properly. When I  put enough items to make only one craft result it works fine but if I put more than enough, like enough to make multiple at once, the items that I put in for the recipe either multiplies within the crafting grid or it doesnt get used up at all. I've tried moving code around, changing values ect. but I can't find out what is causing the issue.

Here is my container class: https://pastebin.com/dvN01bEt

Here is my recipe class: https://pastebin.com/GKZFENZT

Here is my recipe type class: https://pastebin.com/SywS2Av1

And here is the serializer for my recipe: https://pastebin.com/6J4ZUZGp
