It would seem the "EDNS ... udp: 4096" query is using dnscrypt-proxy but the 
"EDNS ... udp: 1280" query is not.

Johnny, possibly you need "no-resolv" in your dnsmasq.conf ?

I assume you have something like:
--
server=127.0.0.1#2053
--
pointing to your dnscrypt-proxy instance.

You may also look into using "proxy-dnssec" if you trust your upstream server's 
DNSSEC since it traveling over a secure dnscrypt-proxy connection.
