Problem with if statements relating to images

So, i need a simple 3 slot inventory system in my game- i tried some of the more efficient methods, but they didnt work, so i opted to use this less efficient, but more reliable for my needs, system (so far there are just two items, called "sun" and "flashlight" respectively. This is my script; I have some playerpref settings as to which are equipped currently. The way it works is; first it checks if the flashlight is equipped; if it is, then the flashlight image (assets.flashlightSprite) goes into the first availible slot.
Then it does the same with the sun item. But the problem is, all the items go to the first slot. If i have flashlight enabled and nothing else, it goes to the first slot. if i have both flashlight and sun enabled, then the sun is in the first slot but the flashlight isnt even there (what is suppost to happen is flashlight in first slot, sun in second slot). if no items are there it works fine. What is the problem with this code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class MenuTypes : MonoBehaviour
 {
     public bool SlotOneEmpty = true;
     public bool SlotTwoEmpty = true;
     public bool SlotThreeEmpty = true;
     public Image Slot1;
     public Image Slot2;
     public Image Slot3;
     public int FlashID = 17;
     public int SunID = 17;
     public ItemAssets assets;
 
     // Start is called before the first frame update
     void Start()
     {
         EquipStuff();
     }
 
     void EquipStuff()
     {
         if (PlayerPrefs.GetInt("flashequipped") == 1)
         {
             if (SlotOneEmpty == true)
             {
                 FlashID = 1;
                 Slot1.sprite = assets.flashlightSprite;
                 SlotOneEmpty = false;
             } else
             {
                 if (SlotTwoEmpty == true)
                 {
                     FlashID = 2;
                     Slot2.sprite = assets.flashlightSprite;
                     SlotTwoEmpty = false;
                 } else
                 {
                     if (SlotThreeEmpty == true)
                     {

                         Slot3.sprite = assets.flashlightSprite;
