DNS verifiaction test

I found a very strange issue with the DNS test to master the level guru.
I set up the subdomain he-test within my namespace but don't even receive a query for that name if I execute the test.
To be sure I tried serveral DNS (google etc.) to verify I'm able to handle DNS requests via IPv6.

Here is what I did:

dig +trace he-test.revenuewire.com AAAA @2001:4860:4860::8888

; <<>> DiG 9.7.3 <<>> +trace he-test.revenuewire.com AAAA @2001:4860:4860::8888

So it shows me that the answer came from ns3 via IPv6, with tcpdump I've confirmed that I've sent the query via IPv6 as well.

23:46:47.605838 IP6 2001:470:b:943:xxxx:xxxx:xxxx:xxxx.45600 > 2001:1af8:4300:a005:49::1.53: 61972 AAAA? he-test.revenuewire.com. (41)
I did the same test with several other ns in Europe with exact the same result.
Everything looks to me like it is working, did anyone come across a similar issue.

I suppose the next step is to bug them and ask, the only error they show on their website is Couln't query NS, which doesn't really help me find out if I still have an issue somewhere.

Thx in advance.
