If you put coal in a hopper, it will only try to go into the top slot of the furnace, even if there's already an item there.
Have you tried putting the hopper into the side of the furnace? My instant thought is that the hoppers are on top of the furnace...
Well either way, you can't smelt coal so you shouldn't be able to put it in the top spot anyway.
Works as intended. Feed the fuel in from the side
