UE4 tutorial

I’m watching the twin-stick tutorial and I’m following every step to the letter but for some reason on the right thumbstick of my ps4 controller snaps the character down when I go to the left it snaps upward when I move the stick up it snaps to the right etc… I’m not sure what else to do. Also, the top-down camera moves with my character when in the video it doesn’t move at all.
