Have you also done tcpdump on two devices to see that config sync request packet is send by the active device and recieved by the standby checked the iQuery part of the article and used iqdump to verify the iquery communication during sync?

Check the /var/log/ltm logs during the sync operation and you can also add them here and also a screenshot with "advanced" view as your previous screenshot is "Basic"
