Wrong Item bug when crafting

When I right click or drag the material on the machine, It says "Wrong Item" in red. Anyone knows how to fix this?

Make sure you're using the correct Material for the recipe you want to craft.

I'm currently not online in game but feel free to add me if you want to ask any questions regarding crafting, & that applies to anybody who may be reading this.

Thanks, Xeoh, I will talk to you IG. So, I figured it out. It's not a bug. I just needed to right click the recipe. I think that they need to put "Right Click it" in the recipe description. But you need to right click the recipe without using the machine.
