Only getting one game object instead of multiple game objects in start of the program

Hi I'm trying to create a 2D game where it has multiple game objects in the start of the game. But I only get one object in the game instead of the supposed no of game objects that should be in the scene.

Here's my code.

public class note_spawner : MonoBehaviour {

 public GameObject noteToSpawn;
 public Sprite[] noteSprites;


 // Start is called before the first frame update
 void Start()
 {
     for(int i=0;i <3; i++)
     {
         spawnRandomNote();
     }
 }

 // Update is called once per frame
 void Update()
 {
    
 } 
 
 public void spawnRandomNote()  
 {
     
     int arrIndex = Random.Range(0, noteSprites.Length);
     Sprite noteSprite = noteSprites[arrIndex];
     string noteName = noteSprite.name;
    
     GameObject newMoneyNote = Instantiate(noteToSpawn);

     newMoneyNote.name = noteName;
     newMoneyNote.GetComponent<note>().noteVal = int.Parse(noteName);
     newMoneyNote.GetComponent<SpriteRenderer>().sprite = noteSprite;

    
 }

}
