Description
Editing a Kea static lease to change the MAC address does not clear the old entry from /var/lib/kea/dhcp4.leases, so when the new device is connected a new IPv4 address is assigned to the device, instead of the one configured in the static lease. The Kea log also shows e.g.:
WARN [kea-dhcp4.alloc-engine.0x218397417400] ALLOC_ENGINE_V4_DISCOVER_ADDRESS_CONFLICT [hwtype=1 30:13:8b:79:56:af], cid=[01:30:13:8b:79:56:46], tid=0x65b2ee64: conflicting reservation for address 10.6.0.4 with existing lease Address: 10.6.0.4 Valid life: 7200 Cltt: 1752320340 Hardware addr: e0:73:e7:c6:6a:24 Client id: 01:e0:73:e7:c6:6a:31 Subnet ID: 1 Pool ID: 0 State: default Relay ID: (none) Remote ID: (none)
The old lease entry is not being removed from dhcp4.leases when the static lease edit form is saved with a new MAC.

Just want to also note that rebooting pfSense does not clear this condition, the only way to fix it currently is to hand edit that dhcp4.leases file
