Why hello @jibe9191 Welcome to the community! 
Usually that happens if the files doesn’t have the correct permissions. If what is happen is that you have a custom module, you save & deploy changes made to the edit/detail view that usually is because the system can’t update the files to accurately reflect your changes and thus shows what was there previously.
Ensure your files permissions and ownership of those files are correct first of all.
sudo chown -R www-data:www-data
sudo chmod -R 755
sudo chmod -R 775 cache custom data modules themes upload
sudo chmod 775 config_override.php
Make sure that www-data is your server’s user, you can quickly check by viewing the Scheduler’s admin page and that’ll show you the correct user to use.
