Help! Values from previous Serialized List<> shows up again after a while using Coroutine

So, I tried doing a basic dialogue script and I attached it to multiple buttons inside my game (Im a beginner by the way)... For some reason. It works for a while, but after switching to the other button and using the similar script, old values from the previous button started showing up.

here's my code.

public Button back; public Button next; public Button close; public GameObject displayImage; public List images; public GameObject displayPanel; public Text textDisplay;

 public List<string> sentences = new List<string>();
 private string[] s = { "Dummy"};
 private int index = 0;
 private int clickcount = 0;
 public float TypeSpeed;
 public AudioSource speak;
 public AudioSource beep;

 // this shows the dialogue box

 public void showDialogueBox()
 {
    
     // I tried saving it to List<> first, then I tried transfering it to an array 
         but same result

     Array.Clear(s, 0, s.Length);
     s = sentences.ToArray<string>(); 
     displayPanel.SetActive(true);

     // to clear previous text from dialogue box
     textDisplay.text = "";

     //For typing effect
     StartCoroutine(Type());
 
     //Adding Button listeners for the dialoguebox

     back.onClick.AddListener(() => backCall());
     next.onClick.AddListener(() => nextCall());
     close.onClick.AddListener(() => enableButtons());
   

   

 }


 private void backCall() {  BackSentence();  }

 private void nextCall() { NextSentence(); }

 private void enableButtons() { index = 0; }


 //Coroutine for typing effect

 IEnumerator Type()
 {
     back.interactable = false;
     close.interactable = false;
     next.interactable = false;
     speak.Play();
     beep.Play();
     int i = 0;

    while( i < s[index].Length)
     {

         textDisplay.text = s[index].Substring(0, i);
         i++;
         yield return new WaitForSeconds(TypeSpeed);
     }
   
     speak.Stop();
     beep.Stop();
     back.interactable = true;
     close.interactable = true;
     next.interactable = true;
     displayImage.GetComponent<Image>().sprite = this.images[this.index];
     indexCheck();
     checkArray();

 }

//load next dialogue

 public void NextSentence()
 {
     if (index < s.Length - 1)
     {
         ++index;
         
         textDisplay.text = "";
         StartCoroutine(Type());
       
     }
     else
     {       
         return;
     }

     textDisplay.text = "";
   
 }

//return previous dialogue

 public void BackSentence()
 {
    
     if (index > 0)
     {
         --index;

         textDisplay.text = "";
         StartCoroutine(Type());
     }
     else
     {
         return;
     }

     textDisplay.text = "";
     
 }
