Belkin RT3200 - missing wlan1

Hi All. I have been running openwrt on my Belkin 3200 for a while. I have upgraded to the latest snalshot ( OpenWrt 22.03-SNAPSHOT r19338-ae64d0624c / LuCI openwrt-22.03 branch git-22.119.37115-66994a5) but appear to be missing wlan1. I have searched the forums and cannot see anyone else reporting this.

Is this an issue with just my device? Does anyone have any steps to troubleshoot/fix?

root@OpenWrt:~# ip link show | grep wla
10: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br-lan state UP qlen 1000

root@OpenWrt:~# dmesg | egrep 'radio|wlan'

This worked on older version r19787-e3e9eb31a2
