Hello, bdemchak


Are you trying to create a subdomain named or an A record named "www" inside the domain


If you create a zone named (by following the same procedure used while created the first domain) it will be automatically placed as a subdomain of (if this one was previously created). 


Check inside the DNS > Zones tab if the "Toogle Hierarquical View" link is being displayed. This can lead you to think that the and are not related subdomains.


If you are trying to create an A record (www) you must access DNS > Zones > Add > Record > A Record and follow the wizard.


Hope this helps.
