In this mode, it is the client, not the DHCP server, which selects its own IPv6. Therefore there are no actual IPv6 leases: dnsmasq just informs the client about the /64 subnet under which the client, not dnsmasq, shall select its address; the client does not inform dnsmasq back. This is /probably/ why the actual address does not show up in the lease file. If you want dnsmasq to control which address the client receives (and possibly log this in the lease file) then you should use DHCPv6 rather than SLAAC.
