DHCPv6 troubles

[InsideTheVoid]

On the DHCPv6 leases page the DUIDs from the clients aren't displayed correctly.
A Windows 8 client with DUID 00:01:00:01:18:1c:59:c5:00:25:22:92:f5:43 (verified with wireshark) displays as 0f:00:01:00:01:18:1c:59:c5:00:25:22:22:92:f5:43 on the web interface.
It adds 0f at the start and 22 in the middle.

dhcpd6.leases

ia-na "\"%\000\017\000\001\000\001\030\034Y\305\000%\"\222\365C" {
  cltt 2 2013/06/25 14:18:43;
  iaaddr 2001:470:1f15:f66::ff0f {
    binding state active;
    preferred-life 4500;
    max-life 7200;
    ends 2 2013/06/25 16:18:43;
  }
}

I left a comment on http://redmine.pfsense.org/issues/2511 but I don't know if that was a smart move because that ticket is closed.

Adding a static lease for the correct or displayed DUID isn't working either. They are always showing as offline and the client gets an other address. Check the duplicate DUID in the picture below.

Finally, if I check 'Deny unknown clients' the server keeps giving leases to all clients.

Could someone point me in the right direction?

I've noticed this as well.

Should I make new bug reports for my issues?
