problem with writing python code to a json file

Please help me, I did a parsing of the site and wanted to collect the words in English and their translation and put them in a json file, but when saving these words in a json file, they begin to repeat themselves and are underlined in red. Here is my code:

import requests
from bs4 import BeautifulSoup
import json

headers = {
    'accept': '*/*',
    "user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36"
}

def get_data():

#req = requests.get(url='https://english4life.ru/anglijskie-slova-po-temam-s-proiznosheniem', headers=headers)

with open("index.html") as file:
    src = file.read()

soup = BeautifulSoup(src, "lxml")

href = soup.find("div", class_="su-row").find_all("a")

projects_url = []
for hrefs in href:
    project_url = hrefs.get("href")
    projects_url.append(project_url)

project_data_list = []
for project_url in projects_url[0:5]:
    req = requests.get(project_url, headers)
    project_name = project_url.split('/')[-1]

    with open(f'data/{project_name}', "w") as file:
        file.write(req.text)

    with open(f"data/{project_name}") as file:
       src = file.read()

    soup = BeautifulSoup(src, "lxml")
    project_data = soup.find("div", class_='entry-con')

    try:
        project_English = project_data.find('tbody').find_all("td", class_='column-1')

        for projects_English in project_English:
            print(projects_English.text)
    except Exception:
        print("No")

    try:
        project_translate = project_data.find('tbody').find_all("td", class_='column-2')

        for projects_translate in project_translate:
            print(projects_translate.text)
    except Exception:
       print("no")

    project_data_list.append(
        {
            'Англиское слово:': projects_English.text,
            'Перевод:': projects_translate.text
        }
    )

    with open("project_data.json", "a",  encoding=('utf-8')) as file:
        json.dump(project_data_list, file, indent=4, ensure_ascii=False)

get_data()
