How do I make Heros continue to level past 5 off creeps?

I'm having trouble in my RPG map with getting my Hero to level past level 5 off Neutral Hostile enemies.

I went to the gameplay constants and deleted all the integers from "Hero XP gained - Creep Reduction Table" but it didn't seem to do anything.

Is there any way to allow continued leveling off creeps without making them non Neutral Hostile?

Thanks!

what you must do is change integer to 100 not delete them

What you also need to do is in Gameplay contents go to the hero maximum level section
