teleport destination differs when player hits trigger from different positions

I simply want my player to teleport from one position to another when it hits the trigger. It seems to work fine, except for one problem. The destination point changes when the player hits the trigger from different positions. For example: When the player hits the 2d box collider on top, the player is teleportet under the destination point I set. If the player hits the 2d box collider on the bottom, the player is teleportet correct. I tried to change form/size of the collieder, but nothing solved the problem. Here the Script I'm using:

 using UnityEngine;
 using System.Collections;
 
 public class Warping : MonoBehaviour
 {
 
     public Transform warpTarget;
 
     IEnumerator OnTriggerEnter2D(Collider2D other)
     {
         ScreenFader sf = GameObject.FindGameObjectWithTag ("Fader").GetComponent<ScreenFader> ();
 
         GameObject
             Player = GameObject.Find ("Player");
         moveplayer
             moveplayer = Player.GetComponent<moveplayer> ();
         moveplayer.canMove = false; 
 
         
         yield return StartCoroutine (sf.FadeToBlack());
 
 
         
         other.gameObject.transform.position = warpTarget.position;
         Camera.main.transform.position = warpTarget.position;
         
         yield return StartCoroutine (sf.FadeToClear ());
         moveplayer.canMove = true;
     }
     }
