Replace text in docx file

Question

Hi, I have this Python code to replace text with context. It seems like the code worked, but not all the text in the Word file has been replaced. I have checked the formatting, but there is no difference between the two paragraphs when the code is not running on the entire document.

import os
import PySimpleGUI as sg
from docx import Document
from docx.shared import RGBColor

def render_files_in_folder(folder_path, contexts):
    try:
        # Get the list of files in the folder
        files = os.listdir(folder_path)
        # Loop through each file and render
        for file_name in files:
            # Check if it's a .docx file
            if file_name.endswith('.docx'):
                file_path = os.path.join(folder_path, file_name)
                print(f"Đang xử lý: {file_path}")
                doc = Document(file_path)
                for context in contexts:
                    replace_text_in_docx(doc, context)
                doc.save(file_path)  # Save the file after rendering
    except Exception as e:
        print(f"An error occurred: {e}")
