Keyboard wake up from sleep problem

Pressing key 'Q', 'W', 'E', 'T', 'Y', 'U' or 'I' to wake up the keyboard from sleep cause the keyboard become unresponsive and NKRO/6KRO indicator to blink although the keyboard is in Bluetooth mode. Pressing other than mention keys will wake up the keyboard normally. I already have try to reset the keyboard, use other device and also use on Android but the problem still persist. My keyboard is Kemove Snowfox (9015) with white stab and side printed legend.

I confirmed this same thing happens to me with those keys. For now, I'm just using spacebar to wake the keyboard. It would be nice to be able to just start typing though.
