I think the coarse/fine action is normal, and built into the pot.This kind of action is usually provided by two pots ganged together, with a slip mechanism between, to disengage the coarse pot. The schematic may show them explicitly, or not, depending on how the pot is built and pinned out.

You can see if it seems to work and is beneficial by using it in a setup. Rotate it to overshoot the desired spot a little, then reverse direction, and it should be much easier to set.When you reach the other limit, the coarse pot will kick in again.
