How do I turn off "Check if target is in View?"

[Macro 3]

My problem is that my hunter does not need line of sight to attack - It can attack through terrain with the bow - no problem

 

Whenever I use grinder, my hunter will target a mob behind the terrain - attack it like normal and then realize the target is not in view, so it moves forward, but then its too close to attack with the bow, so it moves back, then the target is not in view again ... it continues to move back and forth...?

 

even when I disable "Check if target is in View?" in the fight profile for the spells, It still tries to always maintain line of sight with the target and causes this problem.  If I disable Pathfinding, combat is fine but I get stuck when trying to loot. Any ideas?
