systemd-networkd IP assignments for wla/usb devs are ignored; using same IP as local eth lan ?

[PGNet Dev <pgnet.dev@xxxxxxxxx>]

 I'm migrating a linux box to systemd-network use,

	uname -rm
		5.6.3-24.ge840c7b-default x86_64

	rpm -qa | grep ^systemd-2
		systemd-234-lp151.26.13.1.x86_64

	systemctl list-unit-files | grep systemd-net
		systemd-networkd-wait-online.service    enabled
		systemd-networkd.service                enabled
		systemd-networkd.socket                 enabled

I've got two ethernet ports, and two USB wifi dongles.

I've config'd

	/etc/systemd/network/20-enp2s0.network
		[Match]
		Name=enp2s0

		[Network]
		DHCP=ipv4
		DefaultRouteOnDevice=true
		IPForward=0
		LinkLocalAddressing=ipv4
		IPv6AcceptRA=0

	/etc/systemd/network/20-enp3s0.network
		[Match]
		Name=enp3s0

		[Network]
		Address=172.30.11.51/22
		IPForward=1
		IPv6AcceptRA=0

	/etc/systemd/network/21-wlp0s16u2u1.network
		[Match]
		Name=wlp0s16u2u1

		[Network]
		Address=172.30.12.51/24
		Gateway=172.30.12.51
		IPForward=1
		LinkLocalAddressing=ipv4
		IPv6AcceptRA=0

	/etc/systemd/network/21-wlp0s16u2u2.network
		[Match]
		Name=wlp0s16u2u2

		[Network]
		Address=172.30.13.51/24
		Gateway=172.30.13.51
		IPForward=1
		LinkLocalAddressing=ipv4
		IPv6AcceptRA=0

the IPs/gateways assigned are identical to what's running on the system, using distro-native networking, prior to the switch to systemd-networkd

on boot

	enp2s0

is correctly config'd from upstream dhcp.

next,

	enp3s0

my lan-facing intfc, is up correctly too

	enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
		inet 172.30.11.51  netmask 255.255.252.0  broadcast 172.30.11.255
		...

no prob with loopback,

	lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
		inet 127.0.0.1  netmask 255.0.0.0
		...

BUT,

the two wlan intfcs ARE up, but configured with the SAME ip/mask as the local lan, NOT the one spec'd in the config

	wlp0s16u2u1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
		inet 172.30.11.51  netmask 255.255.252.0  broadcast 172.30.11.255
		...

	wlp0s16u2u2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
		inet 172.30.11.51  netmask 255.255.252.0  broadcast 172.30.11.255
		...

clearly, others are config'ing wlans.

what needs to be changed/added in my config to get those wlan IPs correctly allocated?
