Is DHCP Hostfile Update Broken in VyOS 1.3-rolling-202005100117

In the rolling release from this weekend host file update doesn’t appear to be working or I misunderstand how it’s supposed to work.

All that i see in the hosts file is a static entry i put there for nas1.example.com but I’d expect one from vm1 and shawns-vm

service {
     dhcp-server {
         hostfile-update
         shared-network-name vm-network {
             authoritative
             subnet 10.0.3.0/24 {
                 default-router 10.0.3.1
                 dns-server 10.0.0.2
                 domain-name example.com
                 domain-search example.com
                 lease 86400
                 range vm-range {
                     start 10.0.3.200
                     stop 10.0.3.254
                 }
             }
         }
     }

vyos@fw1:~$ show dhcp server leases
