At this point, the INPUT chain for ipv4 looks properly:
$ iptables -L INPUT
Chain INPUT (policy DROP)
target prot opt source destination
ufw-before-logging-input all -- anywhere anywhere
ufw-before-input all -- anywhere anywhere
ufw-after-input all -- anywhere anywhere
ufw-after-logging-input all -- anywhere anywhere
ufw-reject-input all -- anywhere anywhere
ufw-track-input all -- anywhere anywhere
but for ipv6, it remains empty:
$ ip6tables -L INPUT
Chain INPUT (policy DROP)
target prot opt source destination
the other chains (ufw-{before,after,track}-{input,output} etc. do exist
for ipv6, though, just the INPUT chain remains empty.
