Decoding V2G packet issue

[1tianmaxingkong1]

I am using the Decoding V2G packet function by ~>>> n=Network()
~>>> n.pcap("CCS.pcapng") command (java -jar V2Gdecoder.jar -w is already working properly) to parse the wireshark packet (the packet is captured by sniffer), but found that the parsed are the same message XML, but obviously can see that the TCP data is not the same, see the attachment for details. So I would like to ask you, which may be the problem, is there a problem with the installation of the software, or is there a problem with the captured CCS.pcapng?
