Can you please add a back-end and FTP access, so I can check and analyze the issues? Thank you!
Q2 & Q3 – It might be an issue with the language. Javascript regular expressions are not very friendly with chinese/persian or other non unicode language characters. I can try to get around it, but I cannot promise a resolution.
Can you please try the following configuration: https://i.imgur.com/KoKlTxh.png
