DUID was added to dhcpv4 in RFC 4361, and a dhcpd that understands the option will treat different DUIDs as separate devices even if they have the same MAC address. You might want to remove "send dhcp-client-identifier = hardware;" from your /etc/dhcp/dhclient.conf (or equivalent) on your Raspberry Pi.
