Training Stream - Creating a Twin-Stick Shooter - Feb. 3rd, 2015

I was following the tutorial and hoping to be able to implement a similar set up with waves of enemies; however, when I test it the blueprint goes right through all the waves but nothing spawns. It does say in the Scene Outliner that they are spawning. I guess what I would like to know is if there is a set up in the game state blueprint that you did not show in the video? Also, there is no delay when the Spawn Timer ends and the Clear Spawn Timer begins and then on to the next waves set up.
