Mobile select and move Object with offset

Hey! I am working on a mobile project and trying to move objects by double clicking on them and then dragging them, while selected and moving the object is supposed to have a little offset on the y-axis to make it clear which object is handled. So far Clickslection and Doubleclick event is working, the movement is also working and the offset but only the first time I select an object it gets the offset. When I select and move it again it just moves around but doesn't get the y-axis offset. The chosen Objects are Rigidbodies & Colliders, so they fall back on their own. But I can't find why the Y-Offset is only applied once per Object-Lifetime.

 if (Input.GetTouch(0).phase == TouchPhase.Ended && _doubleClickActivated == true)    
         {
             _selectedObject.transform.GetChild(0).gameObject.GetComponent<Rigidbody>().isKinematic = false;      
             _selectedObject.transform.GetChild(0).gameObject.GetComponent<Rigidbody>().detectCollisions = true;
 
             _selectedObject.layer = 0; 
 
             if(_selectedObject.transform.childCount > 0)
             {
                 _selectedObject.transform.GetChild(0).gameObject.layer = 0;    
             }
 
             if(_selectedObject.transform.GetChild(0).childCount > 0)
             {
                 _selectedObject.transform.GetChild(0).GetChild(0).gameObject.layer = 0;
             }
 
             _selectedObject = null;     
             _objSelected = 0;   
             _objectFix = true;             
             _doubleClickActivated = false;   
         }
 
         if (_objectFix == false)   
         {
             if(_objSelected == 1)   
             {
                 RaycastHit hit;
                 Ray ray = _cam.ScreenPointToRay (touch.position);   
                 if (Physics.Raycast(ray, out hit))          
                 {
                     _selectedObject.transform.GetChild(0).gameObject.GetComponent<Rigidbody>().isKinematic = true;      
                     _selectedObject.transform.GetChild(0).gameObject.GetComponent<Rigidbody>().detectCollisions = false;
                     
                     _selectedObject.transform.position = new Vector3(hit.point.x, hit.point.y+0.2f, hit.point.z);       
                 }
             }
 
         }

Is the code I came up with for moving the object. Since the Doubletap & Object Detection seems to work fine I assume the mistake lies within that part. All the selection code does is raycast on the finge position, move the hit object to the Raycast ignore layer and save a reference to the selected object.

If anyone could find out what the problem with the offset only applying once that would be awesome :)

EDIT: Oh forgot to mentiont that the code is part of the update function, in case that is relevant.
