have this problem

This was if I constructed a wall while enemies were already  heading towards that opening. When starting a new round the enemies do walk to the right

If enemys are already on the left, they usually keep attacking the wall and do not walk around to the right. (from personal experience at least)

This is because the enemy AI is really simple and trys to find the path of least resistance. I usually have a really powerful turret setup with holes on either side, and put walls on any other openings. the enemys assume they can walk through the holes on either side, but get obliterated by the turrets.
