You have a cluster object NEWYORK-CLUSTER which consists of newyorkfw1 and newyorkfw2, I suppose. Open NEWYORK-CLUSTER object properties, go to Topology tab, click Edit button. There is eth6 in the list of interfaces, what type of interface is set there, cluster/private/sync? Cluster interfaces must have cluster virtual IP address defined. Right click on it, choose Edit interface, go to Topology tab, define topology. Be careful, as if you incorrectly define topology you might block access to the firewall. If it is not a cluster interface, you need to do the same for eth6 interface of the second member of the cluster.
Also if you got some topology, but didn't get the correct one, probably it is configured in a wrong way on devices themselves.
I would highly recommend to read Admin Guides before configuring firewalls.
