I forgot to raise the level in syslog.conf. New logfile with more details

I think 1) and 2) is because of an issue with my ISPs DHCP server. It
advertises unicast but does not reply to unicast requests. And the first
lease it sends contains an empty IA.

I attached a pcap file which with the DHCPv6 packets. I captured it with:
tcpdump -ni em2 -s 1500 -w /var/log/dhcpv6.dump "ip6 and ( port 546 or port 547 )"

New log with more information:
