all-nameservers flag weird output

[LizIzhikevich]

when I run the following command with the new --all-nameservers flag
echo "google.com" | ./zdns A --iterative --retries=10 --all-nameservers | jq

I get the following output which seems to have duplicate entries/ entries that have no protocol/resolver field. @vishalmohanty do you know what is going on? can you investigate?
