Changing Rect Position in code causes object to disappear? (C#)

So what i'm trying to do is create a searchable inventory which i have done, but then place the item or in this case image with a text element at the top of a scroll view since there is no way for it to move automatically when your setting the others setactive to false. Therefore I tried changing the rect transform position on the y to 0 since it was anchored to the top center where the sword ui element would be.

Here is the script with the correct line outlined.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class SearchBag : MonoBehaviour {
 
     public InputField searchBar;
     public ScrollRect bag;
 
     void Start()
     {
         searchBar.onEndEdit.AddListener(delegate {ReturnText(searchBar);});
     }
 
     void  ReturnText(InputField input)
     {
         for (int i = 0; i < bag.content.childCount; i++) 
         {
             if (searchBar.text == bag.content.GetChild (i).gameObject.name) 
             {
                 bag.content.GetChild (i).gameObject.SetActive (true);
 
                 //This should be setting the rect position to its current x, 0, 0. 
                 //Dont ask why i did vector3 on a ui element ;)
                 //===========================================================================
                 bag.content.GetChild (i).gameObject.GetComponent<RectTransform> ().position = 
                     new Vector3 (bag.content.GetChild (i).gameObject.GetComponent<RectTransform> ().position.x, 0, 0);
                 //============================================================================
 
             } 
             else if (searchBar.text == "")
             {
                 bag.content.GetChild (i).gameObject.SetActive (true);
             }
             else 
             {
                 bag.content.GetChild (i).gameObject.SetActive (false);
             }
         }
             
     }
 }

However as seen in this photo it sets the y value to -600 for whatever reason 0 should be correct as that is the y value of the sword ui element.
