Reply-To not working with CF7 emails

Hello, thanks so much for creating great product in the first place.
I use plugin only for emails and I do have it working, but when I send emails from CF7 form, Reply To is not the email I specified, but rather the email adress that is sending the mail.
Now, the reason I am opening a ticket here is because I have exactly same setup on same website with another plugin that utilizes Google Services and then it works as intended.

I’ve been searching for hours for solution but nothing can help. Is there anything you can do about this and have you noticed this happening if you use the plugin with CF7?

Thanks so much!
