Malformed Packet Error in your example data

Hi, ---> I opened the tnt-call-deciphered.pcap file that you uploaded with wireshark. ---> Then I opened the osmo-gmr code. I got a wireshark output myself using tnt-call-268-93600.cfile , tnt-call-267-93600.cfile and the password. ---> In the resulting wireshark output, the section with (CC) Setup appears as Malformed Packet. a) What is the cause of the Malformed Packet problem? b) How can I fix this problem?
