bss-minrate command isn't changing the basic rate set in Unleased 200.18.x firmware

[Devinator]

I've configured three SSIDs, one per band (2.4G, 5G, 6G), and for each SSID I have the bss-minrate configured for 24M. The AP radios are still announcing the basic rate set as default (2.4G = 1, 2, 5.5, 6, 9, 11, 12, 24) (5G = 6, 12, 24), (6G = 6, 12, 24). I'm using WiFi Explorer Pro to see this, but of course WireShark shows the same. Has anyone else run into this? Is there something I'm missing? Thanks!
