What's wrong code if-else with tag script ?

Hello I have the right panel and the wrong panel, the panel is used to check whether the object is dragging and dropping in the right slot. but in this code, when I run the wrong panel it always appears first, before I drag and drop the object. even though I have set it to be inactive. what should I fix ?

using UnityEngine; using System.Collections; using UnityEngine.EventSystems; using UnityEngine.SceneManagement;

 public class CekBenar3 : MonoBehaviour
 {
     public float delay = 1;
 
     [SerializeField]
     private GameObject PanelBenar;
 
     [SerializeField]
     private GameObject PanelSalah;
 
     void Start()
     {
         PanelBenar.SetActive(false);
         PanelSalah.SetActive(false);
     }
 
     void Update()
     {
         if (Slot1.cek1 && Slot2.cek2 && Slot3.cek3)
         {
             GameObject objek1 = GameObject.FindGameObjectWithTag("Benar1");
             GameObject objek2 = GameObject.FindGameObjectWithTag("Benar2");
             GameObject objek3 = GameObject.FindGameObjectWithTag("Benar3");
 
             if (objek1.transform.parent.tag == "Jawab1" && objek2.transform.parent.tag == "Jawab2" && objek3.transform.parent.tag == "Jawab3")
             {
                 PanelBenar.SetActive(true);
             }
             else
             {
                 PanelSalah.SetActive(true);
             }
     }
 }
