IPv6 flow

Hello,

This is my settings but didn't get IPv6(IPv4 works fine) flow

nprobe.conf
--zmq="tcp://*:5551"
-i=none
-n=none
--collector-port=2055
-V=9
-T="%EXPORTER_IPV4_ADDRESS %EXPORTER_IPV6_ADDRESS %IP_PROTOCOL_VERSION 
%IPV4_SRC_ADDR %IPV6_SRC_ADDR %IPV4_DST_ADDR %IPV6_DST_ADDR 
%IPV4_NEXT_HOP %IPV6_NEXT_HOP %INPUT_SNMP %OUTPUT_SNMP %IN_PKTS 
%IN_BYTES
  %FIRST_SWITCHED %LAST_SWITCHED %L4_SRC_PORT %L4_DST_PORT %TCP_FLAGS 
%PROTOCOL %SRC_TOS %SRC_AS %DST_AS %IPV4_SRC_MASK %IPV6_SRC_MASK 
%IPV4_DST_MASK %IPV6_DST_MASK"

ntopng.conf
-i="tcp://127.0.0.1:5551"
-i="tcp://127.0.0.1:5552"
-G=/var/run/ntopng.pid
-m=192.168.0.0/24
-m=172.16.0.0/16


Anything missed here ?

Thanks in Advanced.
