Ring Alarm base EU ring LED not showing anything

HiI used to get blue circle light in disarmed mode and red circle light in alarm mode, then for some reason over the past couple of months the light was fading, then displaying one side red one side blue and now nothing at all. The settings have the LED brightness up high, all functionality still works but the LEDs are not working. Is this a known problem or a faulty unit? Yes, I could reset to see if that fixes it but it's a bit of a pain for the sake of some LEDs when the system itself is working.Darren
