Does the Aura HD have a button for the light? If so, try that. If I remember rightly, the light icon on the Glo disappears when I use the button to turn the light off (but it's been a long time since I tried this).
Otherwise, have you restarted the device? And you can try manually reinstalling the firmware package. That seems to fix a few weird little things like this. Make sure you get the right package, and use all of it.
