LORAWAN_RGB and sleep

Hi,
i use CubeCell_Board with Arduino IDE. In the LoraWan sketch I have the following sleepMode current measurements :
LORAWAN_RGB -> ACTIVE 3 micrAmp
LORAWAN_RGB -> DEACTIVE 798 microAmp
Also if Lorawan_RGB option is DEACTIVE, the pin GPIO4 is high.
Hub.

If the LED is not useful, it is preferable in energy saving, to deactivate the led.
But the lowpower mode with LoRaWan.sleep is much higher than 3.5microAmp.
Is this a software bug or should i remove the led on the board?
