Help with Prefab script running on wrong instance...

Thanks in advance to anyone who takes the time to help on this. This is my first post for assistance, so I hope I'm not breaking any rules and not posting incorrectly. I have searched Google for similar problems, but have not found any so, here it goes...

Problem:

I have a teleporter that both players and enemies can use. It activates when a player or enemy steps into the activation collider. When it activates it is supposed to enable a script on the player or enemy that entered the activation collider.

It works fine with just the player. It works fine with just 1 enemy. The problem is that when 2 enemies instantiated from the same prefab (slime) enter the activation collider at the same or different times, only the script on the first slime gets called.

This results in the script being fired on the first slime and not the second. Ever.

The teleporter script:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class TeleportPad : MonoBehaviour {
 
     public float timeToReachDestination;
     public TeleportPad linkedTeleporter;
     public Transform arrivalZone;
     public Color teleportColor;
     public bool recieving = false;
 
     void OnTriggerEnter2D(Collider2D other)
     {
 
         if (!recieving) {
                         string tag = other.tag;
                         if (tag == "Player" || tag == "Enemy") {
                 
                                 GameObject p = other.transform.root.gameObject;
                                 Teleport t = p.GetComponent<Teleport> () ? p.GetComponent<Teleport> () : p.GetComponentInChildren<Teleport> ();
                 
                                 if (t && !t.teleporting) {
                                         if (linkedTeleporter && arrivalZone) {
                                                 t.LinkInfo (timeToReachDestination, arrivalZone, linkedTeleporter, this, teleportColor);
                                                 t.enabled = true;
                                         } else {
                                                 Debug.LogError ("Teleport Failed! Not all variables established for " + name);
                                         }
 
                                 } else if(t && t.teleporting)
                 {
                     t.teleporting = false;
                 }
                 
                 
                         }    
                 }     
         }
 
 
 
     public void Disable(float time)
     {
         if(!recieving)
             StartCoroutine (DODisable (time));
     }
 
     IEnumerator DODisable(float time)
     {
         Debug.Log ("Telepad disabled");
         recieving = true;
         yield return new WaitForSeconds (time);
         recieving = false;
         Debug.Log ("Telepad enabled");
     }
 
 
 }
