Could someone please clarify what the new setting „unguided objectives“ does and what ON means?

So according to the description ON means that „Locations are NOT initially shown by exploration beams.“

But if so, why is the setting set to OFF on Pathfinder difficulty and ON on Adventurer difficulty? I assume that they messed up the description, because usually the description changes when changing the setting. In this case I assume it always shows the description for OFF.

If so Ubisoft please fix the description. Its so unclear to me.
