GL-MT3000 4.1.2 - Luci MTK wireless interface configuration

The MTK access policy in the luci page doesnt persist

I set access white list of mac addresses, if I turn off say 5G wireless and turn it on, the list is gone.

Is there another way for me to set white/black access list for a specific wireless interface?

I would kindly ask here as well if it is possible to combine the settings of this section in the original wireless section of LuCi.
I’ve seen the MU-MIMO settings in the MTK menu, and don’t think I’ve ever seen them in the OpenWRT menu (maybe only for unexperience with capable devices like this), but maybe it is possible to combine them together in the original OpenWRT Wireless section?
Ease of use would spike up.
