1.12 and Secondary Controls in Settings | Input

[maddog59]

I re-installed KSP as 1.12 and in Settings | Input set the second column of Translate controls to my numeric keypad. (7=up, 1=down, 4=left, etc.) When I tried to use them in my game it didn't recognize the input, only the default K/I/J/L/H/N controls. Pressing the NumLock key only  switched between doing nothing to swinging the view around. I shut down and restarted the game with no effect, and of course I used the Apply and Accept buttons.

The only way I could get the numeric keypad to control the RCS was by replacing the default controls (in the first column) with the numeric keys.  Any entries in the second column are ignored.

Is this a minor bug? Or have I forgotten some part of modifying the settings?
