GameObject array

I'm trying to create a spawner but for some reason my array doesn't work.

 public class spawner : MonoBehaviour {
     public GameObject[] enemies;
     public Vector3 spawnValues;
     public float spawnWait;
     public int startWait;
     public float spawnMostWait;
     public float spawnLeastWait;
     int randEnemy;
     public bool stop;
 
     // Use this for initialization
     void Start () {
         StartCoroutine (waitSpawner ());
     }
     
     // Update is called once per frame
     void Update () {
         spawnWait = Random.Range (spawnLeastWait, spawnMostWait);
     }
     IEnumerator waitSpawner()
     {
         yield return new WaitForSeconds (startWait);
         while (!stop) {
             randEnemy = Random.Range (0, 2);
             Vector3 spawnPosition = new Vector3 (Random.Range (-spawnValues.x,spawnValues.x), 1, Random.Range (-spawnValues.z, spawnValues.z));
             Instantiate (enemies[randEnemy], spawnPosition + transform.TransformPoint (0, 0, 0), gameObject.transform.rotation);
             yield return new WaitForSeconds (spawnWait);
         }
     }
 }

For some reason the two Element 0 and Element 1 is missing (not my work's picture)

Thanks in advance :)
