Trouble with anchored Position

Unity Engine
1 
    row = 0; counter = -1;
            if (ASuitedCardsList.Count > 0) {
            for(int i = 0; i < 1;  i++)    {
                for(int j = 0; j < totalSuitedA; j++){
                    counter++;
                        Debug.Log ("8" + j);
           
                        ASuitedCardsList[counter].GetComponent<RectTransform>().anchoredPosition3D = new Vector3(640 + row * 30, 170 +  j * -30,6);
   

                    ASuitedCardsList[counter].SetActive(true);  
               
                    }}}

First time I display these buttons they are in the right place.
Second time I loop over the above code the buttons seem to start off at the position the last button was created even though the Vector3 position is exactly the same.
Am I correct in saying that the anchoredposition starts where the last anchoredposition was set?
What do I need to do so that the buttons don’t move when displayed for the second time?

For information:

Originally the gameObjects that I get to display in the above code are initialised by the following code:

trans = go1.GetComponent<RectTransform>();
                go1.transform.SetParent (GameObject.FindObjectOfType<Canvas> ().gameObject.transform, false);
                trans.anchorMax = new Vector2(0,1);
                trans.anchorMin = new Vector2(0,1);
                RectTransformExtensions.SetPositionOfPivot(trans, new Vector2( 0.5f, 0.5f));
                RectTransformExtensions.SetHeight(trans, 30);
                RectTransformExtensions.SetWidth(trans, 30);
                go1.GetComponent<RectTransform>().anchoredPosition = new Vector3(x2 + 20, y - 60, 6);

Hi there, I’m curious - is there a specific reason you are using anchoredPosition3D?

It seems you have some sort of card objects (which I guess wouldn’t stretch or scale).

You could just use Transform.localPosition to move them relative to parent or Transform.position, if they don’t have parent (other than canvas).

I didn’t check your for loop, but other than that, positions should work just fine, I think.
