Pressing two buttons on the xbox D-pad but not moving both directions at once

I already set up my Input manager. Lets say i press the Up arrow and Right arrow on my keyboard, the player will take in both those inputs. When i use the xbox controller and press Up and Right on D-pad it only takes in the first input pressed and ignores the other.

This is the code i have on my player:

     public float jumpSpeed = 15f;
     public Rigidbody rb;
     bool isJumping = false;
     Animator anim;
 
     // Use this for initialization
     void Start () {
         rb = GetComponent<Rigidbody> ();
         isJumping = false;
         anim = GetComponent<Animator> ();
     }
 
     // Update is called once per frame
     void Update () {
 
         if (Input.GetKey ("up") || Input.GetAxis("Horizontal") == 1) {
             transform.Translate (Vector3.forward * 1 * Time.deltaTime);
             anim.Play("rabbit_move");
         }
 
         if (Input.GetKey ("down") || Input.GetAxis("Horizontal") == -1) {
             transform.Translate (Vector3.back * 1 * Time.deltaTime);
             anim.Play("rabbit_move");
         }
 
         if (Input.GetKey ("right") || Input.GetAxis("Turn") == 1) {
             transform.Rotate (0, 200 * Time.deltaTime, 0, Space.World);
         }
 
         if (Input.GetKey ("left") || Input.GetAxis("Turn") == -1) {
             transform.Rotate (0, -200 * Time.deltaTime, 0, Space.World);
         }
 
         if (Input.GetKeyDown ("space") && isJumping == false || Input.GetButton("Jump") && isJumping == false) {
             isJumping = true;
             rb.AddForce (Vector3.up * (jumpSpeed * 2.2f));
             anim.Play("rabbit_jump");
         }
     }
 
     void OnCollisionEnter(){
         isJumping = false;
     }
