It is recommended that the Mobility Master is on later versions than that on the managed devices. In this case, the MD is running later firmware. The setup you have is supported, with some limitations.
There was an issue that got resolved with 8.3.0.0 that showed the opposite problem ... the MM would report an AP as down when the MC showed the AP correctly as up.
