[Python] Default Text re-appears after being overwritten

I am trying to extract bus prices between 2 cities in Ontario, Canada. I am using Selenium/Python to do this:

The website is here and it has default cities and dates.

Here is my Python code:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.keys import Keys
import time

url_flixbus = 'https://www.flixbus.ca/'

# new input values
input_origin = 'Ottawa (VIA Rail)'
input_destination = 'Sudbury, ON'
departure_date = 'Sat, Sep 20'

driver = webdriver.Chrome()
driver.maximize_window()
driver.get(url_flixbus)

# click "Accept Cookies" button
cookie_btn = driver.find_element(By.XPATH, '//*[@id="uc-center container"]/div[2]/div/div/div/button[2]')
cookie_btn.click()

# overwrite values
origin = driver.find_element(By.ID, 'searchInput-from')
origin.clear()
time.sleep(1)
origin.send_keys(input_origin)
time.sleep(1)
#origin.send_keys(Keys.ENTER)

destination = driver.find_element(By.ID, 'searchInput-to')
destination.clear()
time.sleep(1)
destination.send_keys(input_destination)
time.sleep(1)

date = driver.find_element(By.ID, 'dateInput-from')
date.click()
time.sleep(1)
date.send_keys(departure_date)
#date.send_keys(Keys.ENTER)

# click 'Search' button
search_btn = driver.find_element(By.XPATH, '//*[@id="search-mask- component"]/div/div/div/div/div[5]/div/button')
#search_btn = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.journey')))
search_btn.click()`


The default values for 'origin' and 'destination are 'Toronto' and 'Ottawa', respectively. I want to change them to 'Ottawa' and 'Sudbury'.

My issue is when I run the 'origin' portion of the code, I see that the value changes from the default value 'Toronto' to the new value 'Ottawa', which is good.

However, when I run the 'destination' portion, the default changes from 'Ottawa' to 'Sudbury', but then I see that the origin textbox reverts back to 'Toronto'.

The same thing happens to the 'destination' box when I try to overwrite the date.

I put in the clear() lines to remedy this problem, but it still persists. I also experimented with telling the program to press "ENTER" like on a keyboard and it still doesn't work as intended (commented out).

What am I missing?
