Order confirmation mail contains attachment with no content by default

Hi!

Order confirmation mail contains attachment with no content by default. Now I have added another attachment (terms and conditions PDF) to order confirmation email, now it has two attachments.
How can I get rid of 0 byte attachment which is attached to all order confirmation email sent to users since installed Opencart 3.0.2.0? Controller file catalog/controller/mail/order.php did not contain any $mail->AddAttachment(...)

The 0 byte filename is constantly changing, for example: 1525019890

Thanks for helping!

Customers are complaining that their Outlook shows there is an attachment (paperclip),
but there is only plain text in the email without an attachment. Why does Outlook show this?
Or asked differently: What is OpenCart sending that causes Outlook to show a paperclip?
How can this be resolved?

By looking into the code or understanding that how the attachment at the first place being included? Is it some extension which is adding?
