show counter global filter delta yes
i see below counters incrementing need to understand which are these drops and why PA is dropping these packets?

flow_fpga_egress_exception_err
flow_fwd_l3_ttl_zero
flow_action_close

Those names are pretty self explaining.
Also description field helps to explain.
For example description for flow_tcp_non_syn_drop says:
Packets dropped: non-SYN TCP without session match
It means that if the first packet in a session is a TCP packet and it does not have the SYN bit set, the firewall discards it (default).
It might help you to get familiar how Palo processes packet.
