Smithing recipe for 2024.1

Hi,
I have a problem. When I create a recipe for the smithing table on mcreator 2024.1, I can't find it in game, so I can't use it to craft, even though it's there in my workspace.
Does anyone know if this is a bug or something I'm doing wrong? 
thanks

NB: this workspace was created on version 2023.4, I've converted it for 1.20.4 (neoforge).
