K55 RGB Numpad Hardware Limitation, or bug?

[monkunashi]

So, there seems to be some type of limitation to the specific keys you can push simultaneously on the K55 NumPad. I first noticed it in a game, and used switch hitter to confirm.

Problem:
If you push multiple keys in 1 row, then other keys in those columns are disabled. Likewise, if you push multiple keys in a column, then other keys in those rows are disabled.

Examples:
If you hold down 7 and 9 (this is on the numpad remember), then the keys 1,3,4, and 6 do not work.

If you hold down 1 and 4, then the keys 2,3,5 and 6 do not work.

Is this a hardware limitation? or some type of bug?

I've tried doing the Fn+F4 reset.
I've tried with and without iCue running.
I'm on the latest version of iCue (3.10.125)

does nobody have a K55 that can check in switch hitter if this is the case for you as well?

can anyone check if there is any similar limitations on any of the other keyboards? I may end up just getting a new keyboard if this is an actual hardware limitation specific to the K55.

Thanks
