Apologies for my poor English.
While using SignalrGB to control the K3 gen II, I noticed many keys lacked LEDs. After using the LED painting function to check, I discovered many buttons were incorrectly marked. When I tried to change the color of the up arrow key, the num 0 key changed color, even though no other button represented the up arrow LED. The same thing happened with many other buttons. I hope you can fix this issue.
