Lightning issue Blackwidow

I'm having a problem with my blackwidow keyboard. The LEDs of some keys (C, alt, page down) remain lit, with low light, even when the total brightness of the keyboard is set to off. The number of keys that remain lit is increasing, even tho i never light up the keyboard. Even if I try to set a new light profile, the keys continue to remain lit with their color (for example ‘’alt’’ remains red). I tried connecting the keyboard to another computer, resetting it, updating the firmware but nothing works. any suggestions?
