I agree, but none of the packets in this capture have the A bit set, so it does
not help testing the decoding of the Encryption Keyid and MAC

Which is not related to the A bit, it simply shows that mode 7 parsing for
MON_GETLIST_1 is wrongly implemented

MON_GETLIST is not incorrectly parsed, it's not parsed at all as only
MON_GETLIST_1 is implemented.
