I've seen that Wireshark can detect protocol packets like Bitcoin and Lightning Network, which are identified in the protocol column. However, my Wireshark is not classifying those packets, it just says tcp/ip or http/json. Does anyone know how to solve that? I want to identify the packets.

Run 2 nodes with different ports on regtest
bitcoind -regtest=1 -port=18333 -datadir=/home/satoshi/node1
bitcoind -regtest=1 -port=18444 -datadir=/home/satoshi/node2
Add node1 as outbound connection in node2
addnode "127.0.0.1:18333" "add"
Run Wireshark and select adapter for loopback traffic capture. You will see some packets with 'bitcoin' protocol.
Example: This is INV message sent by node2 to node1 when I generated a block using generatetoaddress 10 bcrt1qugkqq2a3lhf58e4pclcf52dgd4e02hpve3vhzs
For reference, Wireshark has included the ability to decode Bitcoin protocol packets since version 1.10.
