My variables arent updating accordingly after I instantiated them

I am trying to instantiate the rock blocks in a grid style and save their information in another script via public ints. The blocks spawn perfectly as intended but the information doesn't save correctly. I set the default values on the prefabs of the gameObjects that I create to 0 and isDead to false. The first 3 gameobject "clones" spawn with all the information to 0 and after the it saves 1 or 2 correctly (might be luck) but then it becomes pretty much random. Any help would be greatly appreciated!

The script that saves the positions :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 //Save the spawn position in the array of all the tiles
 public class TileInformation : MonoBehaviour
 {
     public int PositionInLayer;
     public int xPositionInLayer;
     public int yPositionInLayer;
     public int layerDept;
     public bool isDead = false;
 
 
 }
 

The script that creates the prefabs (Only pasting the part that isn't working as intended)

     //Values to make the grid
     public int amountOfLayers;
     public int sideSize;
     public int heightSize;
     private int layerCounter = 0;
 
 
     //The tiles to spawn
     public GameObject SandStoneTile;
     public GameObject LightRockTile;
     public GameObject RockTile;
     public GameObject SandFloor;
 
     //Gets us the initial posiiton
     public Transform initialPosition;
 
     //Get all the selected tiles
     GameObject[,] allTiles;
 
 
     private void Start()
     {
 
         //while we haven't ocupied all the layers
         int blocksSide;
         int blocksHeight;
         int arrayCounter;

         //Fill all the layers with blocks
         while (layerCounter != amountOfLayers)
         {
             blocksSide = 0;
             blocksHeight = 0;
             arrayCounter = 0;
             
             //while we havent ocupied all block in a certain layer
             
          
             while (arrayCounter != heightSize * sideSize)
             {
 
                 //Get random gameObjectTile
                 GameObject SelectedObject = RandomPicker();

                 //Instantiate our random Object
                 Instantiate(SelectedObject, new Vector3(initialPosition.position.x + blocksSide, initialPosition.position.y + blocksHeight * -1, 1 * layerCounter),Quaternion.identity);
 
                 //Put the newly created block into an array. 
                 allTiles[layerCounter ,arrayCounter] = SelectedObject;

                //I used this to see if the numbers are set correctly which they are!
                 Debug.Log("Counter:" + arrayCounter + "GameObject:" + SelectedObject.name + "Positionx:" + blocksSide + "Position y :" + blocksHeight);
 
                 //This will save where in, another script, a determained clone gameobject is 
                 TileInformation TilePosition = SelectedObject.GetComponent<TileInformation>();
                 TilePosition.layerDept = layerCounter;
                 TilePosition.xPositionInLayer = blocksSide;
                 TilePosition.yPositionInLayer = blocksHeight;
                 TilePosition.PositionInLayer = arrayCounter;
 
 
                 //Increment to the next position
                 arrayCounter++;
                 blocksSide++;
 
                 //if we get to the last position in the grid, we go down if it isnt the last position
                 if (blocksSide == sideSize && arrayCounter != heightSize * sideSize)
                 {
                     blocksSide = 0;
                     blocksHeight++;
                 }
                
             }
             layerCounter++;
         }
 }
