Error that always happend

Hi, I today turn on my MCreator and wanna continue in my modpack. I add new recipe, new way how to get stick, cause i add new wood to game.

Previous time it work perfect, Log,planks and recipe for planks. Today I wanna just add stick(basic one) from my new planks.

When I did, error appear. (I did same way as first recipe, no error with that first one). So i remove it, but error keep in MCreator.
