Hashcat - separator unmatched running pmkid 16800 crack

Question

I'm working on cracking a pmkid file. I have collected pcap file using bettercap.

Then convert using this:

hcxpcaptool -z bettercap-wifi-handshakes.pcap.pmkid bettercap-wifi-handshakes.pcap

They appear to convert:

summary:
--------
file name....................: bettercap-wifi-handshakes.pcap
file type....................: pcap 2.4
file hardware information....: unknown
file os information..........: unknown
file application information.: unknown
network type.................: DLT_IEEE802_11_RADIO (127)
endianness...................: little endian
read errors..................: flawless
packets inside...............: 185
skipped packets..............: 0
packets with GPS data........: 0
packets with FCS.............: 6
beacons (with ESSID inside)..: 7
probe responses..............: 6
EAPOL packets................: 172
EAPOL PMKIDs.................: 10
best handshakes..............: 5 (ap-less: 0)

4 PMKID(s) written to bettercap-wifi-handshakes.pcap.pmkid

I then try to run hashcat against it and it returns "separator unmatched" for all of my entries. This is a simple 2 digit test below. What is going on here?

hashcat -m16800 -a3 -w3  bettercap-wifi-handshakes.pcap.pmkid %d%d --force

How about reading changelog or help menu:

Due to hashcat changes:
"WPA/WPA2 cracking: In the potfile, replace password with PMK in order
to detect already cracked networks across all WPA modes"

hcxpcaptool: added new option -k to convert dumpfile to new hashcat PMKID format

-k <file> : output PMKID file (hashcat hashmode -m 16800 new format)
-z <file> : output PMKID file (hashcat hashmode -m 16800 old format and john)

use hcxhashcattool to convert old 2500 and old 16800 potfile to new hashcat potfile Format:
-p <file> : input old hashcat potfile
            accepted potfiles: 2500 or 16800
-P <file> : output new potfile file (PMK:ESSID:PSK)

hcxhashcattool -p oldhashcat.2500.pot -P newhashcat.potfile 
hcxhashcattool -p oldhashcat.16800.pot -P newhashcat.potfile
