Hi and welcome 🙂
Sorry to see you’ve run into troubles. As always, it’s best you have backups prior to overwriting files via FTP. Your host might have a backup of your site that contains the overwritten files.
In this instance, it’s required you review our Testing for conflicts guide and reply back with what you find out.
Lastly, I notice you have version 4.3.2 of PRO installed. It’s recommended you update to the latest version (4.3.4) and retest to see if the behavior persists.
Please keep me updated and have a great evening. Cheers!
