Display filters for application protocols

Hello to the community, I am doing some testing for the Diameter protocol and I noticed interesting behaviour of the display filters. I noticed that if I run tshark -r mypcap.pcap -R "diameter.cmd.code==302" then the output contains afterwards also Diameter packets with different diameter.cmd.code. I am not sure if it is actually a bug and how tshark handles this filtering for application protocols. E.g.: If there is a packet on containing more Diameter (or other application protocol) messages on IP (or possibly TCP) level, how is this will the display filter filter all of them? Just for the illustration: 1 TCP packet: Diameter message 1 (LIR), Diameter message 2 (MAR), Diameter message 3 (SAR) Running tshark -r mypcap.pcap -R "diameter.cmd.code==302" ... # so filtering out the LIR messages which have message code 302 Should the tshark produce a list of LIR messages only?
