Scroll view script wont show button images

Hi all of you I am making mobile game and when I was working in UI I had issue this scroll view -> content have 3 button images and texts like this but when I start it game doesnt show the images

 using UnityEngine;
 using UnityEngine.UI;
 
 public class swipe_menu : MonoBehaviour
 {
     public GameObject scrollbar;
     private float scroll_pos = 0;
     float[] pos;
 
     // Start is called before the first frame update
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
         pos = new float[transform.childCount];
         float distance = 1f / (pos.Length - 1f);
         for (int i = 0; i < pos.Length; i++)
         {
             pos[i] = distance * i;
         }
 
         if (Input.GetMouseButton(0))
         {
             scroll_pos = scrollbar.GetComponent<Scrollbar>().value;
         }
         else
         {
             for (int i = 0; i < pos.Length; i++)
             {
                 if (scroll_pos < pos[i] + (distance / 2) && scroll_pos > pos[i] - (distance / 2))
                 {
                     scrollbar.GetComponent<Scrollbar>().value = Mathf.Lerp(scrollbar.GetComponent<Scrollbar>().value, pos[i], 0.1f);
                 }
             }
         }
 
 
         for (int i = 0; i < pos.Length; i++)
         {
             if (scroll_pos < pos[i] + (distance / 2) && scroll_pos > pos[i] - (distance / 2))
             {
                 Debug.LogWarning("Current Selected Level" + i);
                 transform.GetChild(i).localScale = Vector2.Lerp(transform.GetChild(i).localScale, new Vector2(1.2f, 1.2f), 0.1f);
                 for (int j = 0; j < pos.Length; j++)
                 {
                     if (j != i)
                     {
                         transform.GetChild(j).localScale = Vector2.Lerp(transform.GetChild(j).localScale, new Vector2(0.8f, 0.8f), 0.1f);
                     }
                 }
             }
         }
 
     }
 }

This is code I am using on content for interactable swift. Code works fine other projects but somehow I can see images like this
