Why does the B-L072Z-LRWAN1 current fluctuate between 2.5mA and 2.9uA when it should be in sleep mode.

I just loaded version 2 of the AT slave firmware on my  B-L072Z-LRWAN1  discovery kit and noticed that the current measured over JP3 which heads to the MCU oscillates between 2.5mA and 2.9 uA every 50 milliseconds. When I flashed the device with older firmware I do not see this. how do I stop this oscillation? Is this a bug in the firmware or a feature of something else?
