From Fred Fierling via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5395 :

The ZigBee security dissector was not recording the short to long address
mappings in Security Headers, preventing the decryption of some payloads. This
patch eliminates the Undecoded warnings in packets 1 and 19 in this test
capture: https://bugs.wireshark.org/bugzilla/attachment.cgi?id=5457

The keys to decrypt these packets are listed in the bug.
