Hard to troubleshoot from afar.  My guess would be that perhaps:

1.	Your nameservers for that zone are IPv6 only, not just the web site.
	(nothing wrong with this)

2.	Their resolver is not ready for an IPv6-only nameserver.
	It's like XP... it'll get a quad-A, but, it won't get anything over IPv6.

I suggest contacting the site administrators and asking them
exactly the question you have above:

"Why don't my perfectly valid AAAA records for onlyv6.com show up on
your site?"
