unity3d - Why my onTrigger is trigering 3 times, even Destroying the other object in the first line?

Question

My ontriggerenter2D is triggering 3 times(instantiating 3 objects), even with me destroying the other object before everything else.

private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.tag == "ShieldPickUp")
        {
            Debug.Log("trigered");
            Destroy(other.gameObject);
            GameObject shieldPU = Instantiate(_shieldPowerUp, transform.position, Quaternion.identity);
            shieldPU.transform.parent = this.transform;
            Instantiate(_shieldTimerSlider, _healthBarCanvas.transform.position + new Vector3(-400, -240, 0), Quaternion.identity, _healthBarCanvas.transform);
            _playerDamager.isPlayerShielded = true;


        }
    }
