Problem switching off Xbee radio

I am using Stalker V2.3 and Xbee pro S2B. I want to switch Xbee off using POWER_BEE jumper and put Stalker MCU into sleep mode. I solder POWER_BEE jumper and INT jumper to wake MCU up with RTC interruption.

The problem is that Xbee does not switch off, pin 1 does not go to GND. It seems to be that it is drawing power from another pin, let’s say TX or RX. Is it a common issue?

Also it gets unconfigured because of the switch. So I have to reconfigure it using X-CTU. Xbee is configured as End Device AT and into sleep/hibernation mode.

Any suggestion?
