Path finding AI walks back and forwards when attacking an enemy. Help?

So, i have a path finding AI that can attack an enemy if the enemy is close enough. When attacking an enemy, my AI uses Path finding so he can avoid obstacles. But there's a problem. When my AI is going to attack his enemy, he constantly walks back and forwards. Help?

**NOTE:**It's at MoveToEnemy() function (line 130-145) were my AI starts chasing the enemy.
