cmdns.dev.dns-oarc.net oddness with windows 10 and bind

[Peter]

So I redone my windows bind setup on a new system and this bug may never 
get fixed but I wanted to post the oddness of this bug.

Bind on New PC as servers 127.0.0.1 for dns on that system 
cmdns.dev.dns-oarc.net reports fine except for IPv6 test OK

I then have two PC's as clients to this DNS bind server 192.168.255.62 
and 192.168.53.2 the internet works fine DNS seems to work fine but 
testing at cmdns.dev.dns-oarc.net shows some failed tests for IPv4.

And it gets odder if on that PC I remove 192.168.255.62 and 192.168.53.2 
and put in 127.0.0.1 setup bind with forwarder only 192.168.255.62 and 
192.168.53.2 then run cmdns.dev.dns-oarc.net it shows as fine!

I just don't get it?
