This is something I'm finding in many forum boards as well as about half of commercial websites; updating top domain recognition to the newly released top domains such as (domain).solutions or (domain).help.
If this can be added to the next release, or if already updated (in this case disregard) it would be a step ahead of many locations.
This is the direct link to the list of current gTDN (generic Top Domain Names) as per ICANN: data.iana.org/TLD/tlds-alpha-by-domain.txt
If you prefer accessing it through ICANN: icann.org/resources/pages/tlds-2012-02-25-en
i believe this is in the list of fixes to be included in the next release. at this time there is no ETA on when that release will be made.
You can fix it meanwhile
