The crafting recipe for the empty palette conflicts with wooden slabs and causes issues. When trying to craft wooden slabs, the palette shows up. The only way to craft wooden slabs is to use the recipe book and make them one by one. Even when shift clicking, it only crafts one and the palette shows up again as the crafting result.
I suggest maybe making the recipe a wooden L instead of a straight line.
