Why doesen't the function get called the second itme?

 So I am trying to spawn some GameObjects in game based on the current player position, essentially trying to make an infinite runner type of game...I made a function `SpawnPylon()` so I can spawn the pylons with it but for some reason the function get's called only once per frame, It does not get called the second time with a different parameter.
 Why does the second call of the function not work? 

This is my code:

     public class CameraScript : MonoBehaviour {
 public float cameraSpeed = 1;
 public float horizontalSpeed;
 private int spawnIndex;
 public float spawnNormPylonDis;
 public float spawnCoinPylonDis;
 private int currPosition ;
 public GameObject[] pilons;
 public GameObject spawnMainPoint;
 public Transform[] spawnPoints;
 public Transform[] coinsSpawnPoint;
 public float enamySpeed;
 private int currentPoint;
 public Transform[] pointPosition;

 // Use this for initialization
 void Start () {
     //This spawns the Pilons.
     spawnMainPoint.transform.position = pointPosition [0].position;
     currPosition = (int) transform.position.z;

 }
 // Update is called once per frame
 void FixedUpdate () {

     spawnMainPoint.transform.position = Vector3.MoveTowards (spawnMainPoint.transform.position, pointPosition[currentPoint].position, Time.deltaTime * horizontalSpeed);

     SpawnPylon (pilons[1],spawnPoints,spawnNormPylonDis,"Check function");
     SpawnPylon (pilons [0], spawnPoints, spawnCoinPylonDis,"Check the second function");

     GetComponent<Rigidbody> ().velocity = transform.forward * cameraSpeed;

     //the next if statements make the Pilons spawn randomly and corectly.
     if (spawnMainPoint.transform.position == pointPosition [currentPoint].position) {
         currentPoint++;
     }
     if (currentPoint == pointPosition.Length) {
         currentPoint = 0;
     }

 }
 /*This function spanws the a GameObject randomly at a GameObject's position and it takes 2 arguments :
 Argument 1: type GameObject 
          2: type Transform[]*/
 void SpawnPylon (GameObject whatSpawn,Transform[] whereSpawn,float spawnDistance,string plm)
 {        
     bool hasSpawnedPylon = false;

     if (currPosition != (int)transform.position.z)
     {
         if ((int)transform.position.z % spawnDistance == 0) 
         {
             Debug.Log (plm);
             if (!hasSpawnedPylon) 
             {
                 //this makes the GameObject spawn randomly
                 spawnIndex = Random.Range (0, spawnPoints.Length);
                 //This is instantiationg the GameObject
                 Instantiate (whatSpawn, whereSpawn [spawnIndex].position, whereSpawn [spawnIndex].rotation);
                 //this makes shore that the GameObject is not spawned multiple times at aproximetley the same position.
                 currPosition = (int)transform.position.z;
             }
         }
     }
     else
     {
         hasSpawnedPylon = false;
     }            
 }

}

Here I have a picture with the script in the inspector:

And here is the console, trying to figure it out by using Debug.Log () for the calls of the function.
