Hello
I Found an error in DNS Manager 3.6 when using - in an domain name, example my name is test-domain.com, the SOA will be blank, but if my domain is testdomain.com, the SOA appear.
Here's some screen shoot of what happen

The domain is working, but it showed error or mxtoolbox saying "Primary Name Server Not Listed At Parent"
Mean while my other domain without - showed the SOA just fine.
Help fix the issue please
