I see my input on my pulverizer is Blue and I have my power furnace hooked up to it, and my output on my pulv is red which sends my pulv materials to my furnace, but then I get some extra pulv material that goes into the slot below my output. I go to settings and change that to red too and the extra pulv materials still sit there and dont transfer to my furnace. How do i fix this so I can send the extra to my furnance?
