Issue on v21.02.1 with wlan0 being DOWN, but disable/enable helps

I have an issue on Omega2sp where I have mt76 device with adhoc, sta and ap all on at the same time. This combo worked great on 19.07.8, but now there's an issue.

After booting, wlan0 appears as DOWN:

4: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master bat0 state DOWN group default qlen 1000
    link/ether 40:a3:6b:c3:f4:eb brd ff:ff:ff:ff:ff:ff

I installed LUCI and there it shows up as "disabled", even if it's not, as Disable button is visible.

If I click on Disable and then Enable, wlan0 comes UP:

11: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 40:a3:6b:c3:f4:eb brd ff:ff:ff:ff:ff:ff

Do a reboot, and it's back to being "disabled", for no reason.
