It is using wicked and fixed address, but IPv6 comes via dhcp or
whatever.
SLAAC - seeing as that IPV6 nameserver is the only non-static entry in
your resolv.conf, I'll venture a guess and say your IPv6 config is
being updated or renewed, which causes your resolv.conf to be updated
too.

The router does DHCPv6 and RADVD. There is also  MLD Snooping
