Policy info is missing in iptables output

[Shellcat-Zero]

Normal output of iptables -xnvL will show lines like:

Chain FORWARD (policy DROP 1110 packets, 141866 bytes)
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)

that indicates the current policy and associated packet/byte counts processed by the policy. This output appears to be missing from a command like iptables -xnvL | jc --iptables. Please advise.

Thanks!
