Yeah, i have started a completely new one (and the class option wasn't checked).
Also i'm using most of your mods (not all of them e.g the electronics mod, which makes the game even more complicated for me) and Angel's refining, which i assume the root cause of the issue...no other mods i'm using can interfere with the recipes (helmod assistant, Information, RSO mod).
I would submit pictures to show you what is available and will be easier to see what's wrong.
Update 1: so i experimented, it seems like that if the Chemicals/intermediate mod is turned on the 5plate to steel recipe is gone for the normal furnace and steel can only be made in the stone chemical furnace which needs steel.
