Question prefab instantiate twice every time i start playing, in addition to it's "if" instantiate method

hi guys, weird thing happening to me rn.
i've created a text object that instantiates every time the player's collider collides with an NPC's, and destroys itself when colliding = null. this works fine, however, every time i start playing, the prefab instantiates twice and stays there. if the player collides with the NPC, it instantiates a third prefab and destroys itself when the player moves and the triggering = null, however the 2 prefabs remain no matter what.
they only destroy themselves when i stop playing.
here are the scripts for the player and the spawner (the NPC's script has no reference to the spawner):
player:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Player : MonoBehaviour
6. {
7.     private GameObject triggeringNpc;
8.     private bool triggering;
9.    
10.     // public GameObject FloatingTextPrefab;
11.  
12.     void Update()
13.     {
14.         if (triggering)
15.         {
16.             if (Input.GetKey("e"))
17.             {
18.                 print("player is interacting with " + triggeringNpc);
19.  
20.             }
21.         }
22.  
23.     }
24.  
25.     //this sentence means that the program will check if the player is triggering with an NPC
26.     void OnTriggerEnter(Collider other)
27.     {
28.      
29.         //this statement comes to check if the 'other' (which is the object we are colliding with) is tagged as "NPC", triggering is going to happen
30.         if(other.tag == "NPC")
31.         {
32.             triggering = true;
33.             //this next line means the the other thing we are interacting with and it's definition is the triggering NPC private variable.
34.             triggeringNpc = other.gameObject;
35.         }
36.         FindObjectOfType<TextSpawner>().OnTriggering();
37.     }
38.  
39.     //this sentence means that the program will check if the player isn't triggering with an NPC
40.     void OnTriggerExit(Collider other)
41.     {
42.         if (other.tag == "NPC")
43.         {
44.             triggering = false;
45.             triggeringNpc = null;
46.             FindObjectOfType<TextSpawner>().OnNotTriggering();
47.  
48.         }
49.     }
50.  
51. }
52.  

spawner:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class TextSpawner : MonoBehaviour
7. {
8.     public GameObject floatingTextPrefab;
9.     GameObject newText;
10.     void Start()
11.     {
12.        
13.     }
14.  
15.     public void Update()
16.     {
17.        
18.     }
19.  
20.     public void OnTriggering()
21.     {
22.        
23.         Vector3 spawnPosition = new Vector3(-3.75f, 2.5f, -133.1f);
24.         newText = (GameObject)Instantiate (floatingTextPrefab, spawnPosition, Quaternion.identity);
25.     }
26.     public void OnNotTriggering()
27.     {
28.         Destroy(newText);
29.     }
30. }
31.  

thanks

 

::Solution::
put FindObjectOfType<TextSpawner>().OnTriggering(); on the if statement that regards wht happens when triggering object of type "NPC".
