LocalPosition change affecting actual Position?

I have an enemy object that constantly follows the player using A*. I wanted to add a little shake to it for the feedback for an electric weapon to give the impression they were just "shocked." So I parented the SpriteRenderer to an empty transform with the Collider and RB. I added the "shake" script to the sprite object to affect it separately from the RB object.

Problem is, the script ends and I want to move the Sprite back to the Collider object's current position. So I assign the localPosition back to (0,0,0), but it instead transports the entire object (including the collider) back to the (0,0,0) of the scene, as if I had altered the actual Position instead.

The enemies are prefabs which for now are being instantiated via a wave spawner. Here's my code if someone can tell me what's up with this:

private float shakeAmount = 0f; private EnemyAI enemyAIClone; private Transform myRef; private Vector3 zero;

 // Use myRef for initialization
 void Awake()
 {
     enemyAIClone = GetComponentInParent<EnemyAI> ();
     myRef = this.gameObject.GetComponentInChildren<Transform>();
 }
 
 void Update()
 {


     if (Input.GetKeyDown(KeyCode.E)) 
     {
         //Test the shake
         StunShake (0.3f, .3f, true);
     }
 }
 
 public void StunShake (float _amnt, float _leng, bool _isExplosion) 
 {
     if (IsInvoking ("BeginShake") == false || _isExplosion == true) 
     {
         shakeAmount = _amnt;
         zero = new Vector3(0,0,0);
         InvokeRepeating ("BeginShake", 0.01f, .02f);

         if(enemyAIClone.stun == false)
         {
             Invoke ("StopShake", _leng);
         }
     } 
 }
 
 // Update is called once per frame
 void BeginShake () 
 {
     if (shakeAmount > 0) 
     {
         Vector3 myPos = myRef.position;

         
         if (Vector3.Distance(myPos, myRef.position) <= shakeAmount/30) 
         {
             myPos = myRef.position + Random.insideUnitSphere * shakeAmount;
         }

         
         myRef.position = Vector3.Lerp(myRef.position, myPos , 1f);
         //myRef.transform.localPosition = Vector3.Lerp(myPos, Vector3.zero , 1f);

     }
 }
 
 void StopShake () 
 {
     CancelInvoke ("BeginShake");

     zero = myRef.GetComponentInParent<Transform>().position;

     myRef.position = Vector3.Lerp(myRef.position, zero , 1f);
     myRef.localPosition = new Vector3 (0, 0, 0);
 }
