Hi,
Why my bluetooth keyboard inactive? Why I can't select it?

I can't check my DREVO KEYBOARD.
Please confirm the latest beta version. (v11.3.1)
How to upgrade to the latest beta version:

Your bluetooth keyboard does not have own vendor id, thus Karabiner-Elements treat it as Apple devices and disable it since Karabiner-Elements ignore Apple pointing devices.
I've changed to enable devices which have keyboard interface.
Yes, its latest. Just downloaded from site.
I updated the beta version.
Please upgrade from Preferences.

I don't see this Devices tab at all? I also have a DREVO Calibur 71 and I'm trying to figure out how to swap the Alt Key and the Windows key. I'm using 10.22.0 of Karabiner.
