Keyboard backlight Icon keeps coming on randomly & can stay for a while then disappear or might go if I press the volume, brightness or keyboard backlight buttons. When it comes up its always at zero (see pic) If I turn up the keyboard brightness it wont allow me to turn it down & then will randomly appear & turn itself down to zero, then will keep appearing & disappearing whenever it feels like it. Extremely annoying. I think my mac is 2015. Have attached pic to show spec.
Any help would be much appreciated as this is driving me mad.
