How do I use output of packet monitor capture to identify which rule or policy blocking the PING

I am unable to ping between LAN zone and Backup Zone. When I check policy from LAN to Backup zone I see Any Any policy. So, PING should not be blocked. Also policy # 27 which is shown in the output of packet monitor capture does not even match with what is going on. So I would like to know if I am misinterpreting the output of packet monitor capture to find cause of PING failure between LAN and Backup zones. Please advise. Thanks in advance.

Unfortunately the contents of the DROPPED line are not especially useful. It definitely does not tell you what policy it is that causes the traffic to be dropped, despite it being obvious to pretty much anybody that that's exactly the kind of information one would hope to see there.
Also, "Policy" could be any of route policy, NAT policy or access policy, but, unlikely to be a route policy if it's a connected network. Unlikely to be a NAT policy between two connected private networks. So probably is access policy.
In the device/log/settings - import the firewall action the logs should then show the action against the firewall rules.
I will try this and update the post.
I have TZ 600 with SonicOS Enhanced 6.5.4.15-116n. This is not the option I see you put in the screenshot or otherwise.
On Gen6 the mentioned settings can be found under Manage → Logs & Reporting → Log Settings → Base Setup, you have to hit the "Import Template" toggle.
