This is caused by the fact that FPP add an upgrade to all Mining Drill of the game (Vanilla or Moded), but the Ore Cleaner can't be upgraded.
I created a fixed version will waiting for Kintharo to release a version with the Mobile Factory compatibility.
You can find the fix here: Factorio Plus Plus fix for Mobile Factory
(I Just added the Ore Cleaner to the data-update.lua)
