Bubble Sort Algorithm Not Sorting LikedList Contents

[JayJayOi]

Hi, I am currently trying to code for this particular question which is
Uncle Tim started his Secondhand Bookstore in 2000. As years passed, the number of books in his store increased significantly. He can no longer keep track of their location in his store. He has approached you to develop a program (in Python) that could help him to keep track of the books.
My Current Codes Are :

class Node:
    def __init__(self,data):
        self.data = data
        self.next = None

    def getData(self):
        return self.data

    def setData(self, newData):
        self.data = newData

    def getNext(self):
        return self.next

    def setNext(self,newNode):
        self.next=newNode

class Book:
    def __init__(self, author, title, bookID):
        self.author = author
        self.title = title
        self.bookID = bookID
        
        
    def __str__(self):
        return 'Author: ' + self.author + ', Title: ' + \
            self.title + ', Book ID: ' + str(self.bookID);
        
    def setAuthor(self, author):
        self.author = author
        
    def getAuthor(self):
        return self.author
        
    def setTitle(self, title):
        self.book = book
        
    def getTitle(self):
        return self.title

    def setBookID(self, bookID):
        self.bookID = bookID
    
    def getBookID(self):
        return self.bookID

class LinkedList:
    def __init__(self):
        self.head = None
        self.size = 0

    def AddBookToFront(self, data):
        print("1")
        newNode = Node(data)
        newNode.setNext(self.head)
        self.head = newNode
        self.size+=1

    def DisplayBook(self):
        print("3")
        tempo = self.head
        while tempo is not None:
            print ("Author Name: " + tempo.getData().getAuthor() +" " +"Title: " + tempo.getData().getTitle()+ " "+"Book ID: "+tempo.getData().getBookID())
            tempo = tempo.getNext()
    
    def RemoveBookAtPosition(self,position):
          # If linked list is empty
          if self.head == None:
              return

          # Store head node
          temp = self.head

          # If head needs to be removed
          if position == 0:
              head = temp.next
              temp = None
              return

          # Find previous node of the node to be deleted
          for i in range(position -1 ):
              temp = temp.next
              if temp is None:
                  break

          # If position is more than number of nodes
          if temp is None:
              return
          if temp.next is None:
              return

          # Node temp.next is the node to be deleted
          # store pointer to the next of node to be deleted
          next = temp.next.next

          # Unlink the node from linked list
          temp.next = None

          temp.next = next
    def AddBookAtPosition(self, data , position):
        cursor= self.head
        temps = Node(data)
        index = 0
        prev = None
        if (position ==0):
            temps.setNext(cursor)
            self.head = temp
        else:
            while (index < position):
                prev = cursor
                cursor = cursor.getNext()
                index +=1
        prev.getNext()
        prev.setNext(temps)
    
    def bubbleSort(self):
        cursor= self.head
        one = cursor.getNext()
        two = one.getNext()
        for i in range(0,self.size):
            for j in range(i):
                if(one.getData().getAuthor() > two.getData().getAuthor()):
                    temp2 = cursor
                    one = two
                    two =temp2

ll=LinkedList()
book1 = Book("AAA","BBB","0001")
#n1=Node(book1)
book2 = Book("CCC", "BBB", "0002")
#n2=Node(book2)
book3 = Book("DDD", "CCC", "0003")
#n3=Node(book3)
book4 = Book("GGG", "FFF", "0004")
book5 = Book("EEE","LLL", "0005")

ll.AddBookToFront(book1)
ll.AddBookToFront(book2)
ll.AddBookToFront(book3)
#ll.AddBookAtPosition(book4, 2)
ll.DisplayBook()
print("After Removing")
ll.RemoveBookAtPosition(1)
ll.DisplayBook()
print("After Adding Value At Position 2")
ll.AddBookAtPosition(book4,2)
ll.DisplayBook()
print("After Adding Value At Position 3")
ll.AddBookAtPosition(book5,3)
ll.DisplayBook()
print("After Sorting")
ll.bubbleSort()
ll.DisplayBook()

The Bubble Sort Code Is Here

   def bubbleSort(self):
        cursor= self.head
        one = cursor.getNext()
        two = one.getNext()
        for i in range(0,self.size):
            for j in range(i):
                if(one.getData().getAuthor() > two.getData().getAuthor()):
                    temp2 = cursor
                    one = two
                    two =temp2
