'DHCPv6 Static Mappings for this Interface' option isn't working (2.4.4-DEV)

I'm using 2.4.4.a.20180724.1706 CE (Virtual pfSense and vPC) and I assigned LAN as IPv6 interface with static IPv6: 2001:db8:1:1::a:1/64. Then I set up DHCPv6 Server with range 2001:db8:1:1::d:0000-2001:db8:1:1::d:FFFF and my Ubuntu received IPv6-address: 2001:db8:1:1::d:2000/128 and I see this Lease into Status/DHCPv6 Leases menu.

DHCPv6 Server config: cat /var/dhcpd/var/db/dhcpd6
option domain-search-list code 119 = text;

default-lease-time 7200;
max-lease-time 86400;

option dhcp6.name-servers 2001:db8:1:1::a:1;

}
ddns-update-style none;

'cat /var/dhcpd/var/db/dhcpd6.leases' showed:

}

Then I tried to create DHCPv6 Static Mappings so I just pressed "Add static mapping" for this dynamic lease (Status/DHCPv6 Leases menu) and set for this static lease IPv6: 2001:db8:1:1::d:24 and pressed Save. After that I saw two Leases into Status/DHCPv6 Leases menu:
- dynamic 2001:db8:1:1::d:2000 is online
- static 2001:db8:1:1::d:24 is offline
both for the same DUID. And I've never saw static lease being online.

With Static Mapping: cat /var/dhcpd/etc/dhcpdv6.conf showed
option domain-name "localdomain";
option ldap-server code 95 = text;
option domain-search-list code 119 = text;

}
ddns-update-style none;

To delete dynamic lease, I stopped interface on my Ubuntu and deleted manualy Dynamic Lease from '/var/dhcpd/var/db/dhcpd6.leases' and restarted DHCPd 'pfSsh.php playback restartdhcpd'. When I run interface on my PC, it again had old IPv6-address (the same as it was from Dynamic DHCP) but nothing inside '/var/dhcpd/var/db/dhcp6.lease'. Static Mapping didn't work at all.

After I deleted static mapping and reinitiated port nothing into Status/DHCPv6 Leases menu but on Ubuntu ifconfig still shows 2001:db8:1:1::d:2000 and inside 'cat /var/dhcpd/etc/dhcpdv6.conf' I still saw Static Mapping entry. So I restarted DHCPd, Static DHCP mapping entry dissappead from '/var/dhcpd/etc/dhcpdv6.conf'. I reinitiate connection from my PC but into Status/DHCPv6 Leases menu there wasn't dynamic lease for my PC and nothing inside '/var/dhcpd/var/db/dhcp6.lease'.
Ping from pfSense for my PC IPv6-address works:

Also I tried all of these steps on 2.4.4.a.20180728.1424 with the same result.
