CISCO SD WAN HSL Can't (yet) decode flowset id

[SorinCeaus]

Logstash v8.15.1 classical VM installation run as a service on RH9.
Netflow codec plugin v4.3.2

Using following config :

input {
  tcp {
    port => 15055
    host => "0.0.0.0"
    codec => netflow {
      versions => [5, 9, 10]
      cache_ttl => 12000
      cache_save_path => "/tmp"
      include_flowset_id => true
      }
  }
  udp {
    port => 15055
    host => "0.0.0.0"
    codec => netflow {
      versions => [5, 9, 10]
      cache_ttl => 12000
      cache_save_path => "/tmp"
      include_flowset_id => true
      }
  }
}

Netflow exporter is a CISCO SD WAN HSL sending v9 and v10 ipfix, template is sent OK (present in pcap) and file is created in /tmp/

cat /tmp/ipfix_templates.cache
{"6|257":[["string","applicationId",{"length":4,"trim_padding":true}],["string","applicationName",{"length":24,"trim_padding":true}],["string","applicationDescription",{"length":55,"trim_padding":true}]],"6|258":[["uint32","ingressInterface"],["string","interfaceName",{"length":33,"trim_padding":true}],["string","interfaceDescription",{"length":65,"trim_padding":true}],["uint32","egressInterface"]]}

but still we get this in logstash-plain.log (of course, it doesn't go away):
