PS4 Left Analog Vertical Not Working (Input.GetAxis("Vertical"))

I'm trying to have the player use a PS4 controller to play. I'm having an issue with the left analog's input.
When I call Input.GetAxis("Vertical"), the value stays at zero when I move the analog stick up and down. However, Input.GetAxis("Horizontal") works completely fine. I've made sure the name is correct in the script and the input settings and tried different controller, and I'm not sure where to go from here.
I have a feeling it's something really dumb on my part. Any tips on how to solve this are greatly appreciated.
Here's my code:
void Update() { var x = Input.GetAxis("Horizontal"); var y = Input.GetAxis("Vertical");Debug.Log("Input.GetAxis(Vertical):" + Input.GetAxis("Vertical"));Movement(x, y, lookX); } public void Movement(float x, float y, float lookX){ // Movementif (canMove == true) { playerAnimations.SetFloat("VelX", x); playerAnimations.SetFloat("VelY", y); transform.position += (Vector3.forward * speed) * y * Time.deltaTime; transform.position += (Vector3.right * speed) * x * Time.deltaTime; transform.Rotate(0, Time.deltaTime * clockwise * lookX, 0); } }
