yes, this could be a conflict. the regular grinding research should give you the possibility to put These chunks into the sorting machine, as you can put the Diamonds in there after the Diamond grinding Research. the Diamond grinding Research Needs the grinding Research
I just checked it out, sorry for late answer.
The both mods are not meant to be for each other. They are content overhauls and i saw, there is not just the grinding thing but some more incompatibilities. Just rename everything would not only create chaos (imagine to have some resources like silver or gold in two different types on the map, incompatible to each others recipe) but also devastate other players research when updating to the new version. I could patch that issue with bobs and fpp but it would only be the tip of the ice mountain for me and all other testers which are playing both mods. I recommend you to chose for one of them.
Bobs if you like complexity,
Fpp if you like easy gameplay
Sorry for that, and also thank you for reporting (even hunt down these incompatibles would lead me into a long maze journey)
