[BUG] Kea DHCP shows the same MAC address for 2 different devices

[marcog]

Hi,
I have 2 IP cameras that are using a static IP address (no dhcp reservations, just a static address).
I can see both of them in the 'Leases DHCPv4' section of the Kea service but according to the UI, both of them have the same MAC address...
I had a look in the Interfaces->Diagnostics->ARP table and the MAC addresses are (correctly) different.
Any idea what's happening?
Thanks
