Domain Attribute not working

I am downloading a file called output.txt and trying to sort into a folder and then rename it with pattern #_domain_nameEXTENSION, but the domain is not showing in the renamed file. It shows up as 1__output.txt. Why is the domain from where I am downloading the file not showing up?

First off, you posted in the wrong forum discussion. This issue is about the software and not this site so please do not post to that forum. I've moved the post here. Secondly, please do not email and post the same issue. Choose one or the other. Since I already replied via email, let's continue the discussion there.
