Particle system rotation/spread not working

Below is the prefab for the particle system for a bullet hit in my game. You can see that the particle spread is about 30 degrees

However, when a bullet hit is actually seen in game, it looks like you see below at the top of the screen, with the particles spreading out in all directions Here is the code I used on the wall collider to instantiate the particle system:

 private void OnCollisionEnter2D(Collision2D collision)
     {
         if (!collision.gameObject.CompareTag("Bullet"))
         {
             return;
         }
         ContactPoint2D contact = collision.GetContact(0);
         Quaternion rot = Quaternion.FromToRotation(Vector3.up, contact.normal);
 
         Vector3 pos = contact.point;
         Instantiate(bulletHit, pos, rot);
         Destroy(collision.gameObject);
     }

I just started Unity and have been trying to solve this issue for an hour to no avail. Thank you for any responses!
