Understanding switch and case functions with Toggle group

Hello, with four toggles in a group and a ChangeToggle function in C# each toggle passes an assigned int. The switch and case seem to work properly changing an enum; although, debug will pass the last result and new result, two debug lines when I'm expecting just one.

Are switch/case a good option compared to if's in this case? Is dual Debug something I can overlook or should I avoid this use?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine.UI;
4. using UnityEngine;
5.  
6. public class Generic
7. {
8.     public enum ItemCategory
9.     {
10.         Item,
11.         Pharmacy,
12.         Packs,
13.         Bank
14.     }
15. }
16. public class EnumsAndToggles : MonoBehaviour
17. {
18.     public Generic.ItemCategory section;
19.  
20.     // Start is called before the first frame update
21.     void Start()
22.     {
23.         ChangeItems(0);
24.     }
25.  
26.     public void ChangeItems(int toggle)
27.     {
28.         switch (toggle)
29.         {
30.             case 1:
31.                 section = Generic.ItemCategory.Pharmacy;
32.                 break;
33.             case 2:
34.                 section = Generic.ItemCategory.Packs;
35.                 break;
36.             case 3:
37.                 section = Generic.ItemCategory.Bank;
38.                 break;
39.             default:
40.                 section = Generic.ItemCategory.Item;
41.                 break;
42.         }
43.         Debug.Log(section + " Section");
44.     }
45. }

Thanks-
