Help I can't get my metallurgic infuser to make steel. It has power and so forth. The two boxes on the left are highlighted yellow and red. I noticed when I was googling how to do this. Every photo and video shows the first box on the left being purple and not yellow. I can stick the ore in the red box just fine it starts to smelt down. just not the coal or charcoal into the yellow box to make the steel. I'm on the latest release of minecraft / using the latest release of this mod as well.
