Displaying object with button

[Edited; thank you YBtheS!]

I have a scriptable object called a "page" that contains both text and an array of "next pages." I'm trying to get this script so that when I click a button it loads the corresponding page in the array, and I can't seem to get it to display. Here's what happens when I click the button:

Click 1

Click 2

So apparently the next page is loaded but not displayed? If anyone can help me figure out what to do it would be amazing

 public class UserInputHandler : MonoBehaviour
 {
     AdventureGame adventureGame;
     [SerializeField] Button a;
     [SerializeField] Button b;
     [SerializeField] Button c;
     Page currentPage;
     Page[] nextPages;
 
     bool pageNamed;
 
     //Start Menu
     public void NewStoryButton()
     {
         //prompt for story name
         //create folder for story pages titled with the story name
         //load new page in editor
     }
 
     //Editor
     void Start ()
     {
         adventureGame = FindObjectOfType<AdventureGame>();
     }
     
     private void PageButtons()
     {
         Page p = adventureGame.GetCurrentPage();
         nextPages = new Page[p.GetNextPages().Length];
         Debug.Log(nextPages.Length);
         nextPages = p.GetNextPages();
     }
 
 
     //A: if adventureGame currentPage has nextPages[0], load nextPages[0], else create new page
     public void A_Button()
     {
         PageButtons();
 
         //if currentPage has nextPage[0] = true, load nextPages[0]
         if (nextPages[0] == null)
         {
             adventureGame.CreateNewPage();
             Debug.Log("New page created");
         }
 
         else
         { //these next two lines are what I've tried so far
             adventureGame.SetCurrentPage(nextPages[0]);
             adventureGame.ManagePage();
             Debug.Log(nextPages[0]);
         }
 
     }
 
     //B: if currentPage has nextPages[1], return true; else false
     public void B_Button()
     {
         PageButtons();
         adventureGame.ManagePage();
 
         // if currentPage has nextPage[1] = true, load nextPages[0]
         if (nextPages[1] == null)
         {
             adventureGame.CreateNewPage();
         }
 
         else
         {
             
         }
 
     }
 
     //C: if currentPage has nextPages[2], return true; else false
     public void C_Button()
     {
         PageButtons();
         adventureGame.ManagePage();
 
         if (nextPages[2] == null)
         {
             
         }
 
         else
         {
             Debug.Log(nextPages[2]);
         }
     }
 
 
     private void DisableButtons()
     {
         PageButtons();
         
         //if nextPages[] has no elements, disable B & C
         if (nextPages[0] == null && nextPages[1] == null && nextPages[2] == null)
         {
             a.interactable = true;
             b.interactable = false;
             c.interactable = false;
         }
         //if nextPages[] does not have elements 0 & 1, disable C
         else if (nextPages[1] == null && nextPages[2] == null)
         {
             a.interactable = true;
             b.interactable = true;
             c.interactable = false;
         }
         //if nextPages[] has all 3 elements, buttons enabled
         else
         {
             a.interactable = true;
             b.interactable = true;
             c.interactable = true;
         }
     }
 
     private void Update()
     {
         DisableButtons();
     }
 
 }

public class AdventureGame : MonoBehaviour { [SerializeField] public TextMeshProUGUI storyText; [SerializeField] Page newPage;
