Why is my wall block remove trapdoors crafting recipe?

I'm not sure what's causing this, but I have a mod that adds a bunch of walls. There are wooden walls, which I made a crafting recipe of 6 blocks at the bottom so that it wouldn't conflict with the trapdoors recipe. But for some reason, MCreator is binding the walls by default to the usual top crafting recipe, which removes the trapdoors one. What's happening, I didn't make that recipe and shapeless crafting is unchecked for all of them. How do I fix this?
