BM71 Power

Greetings,
 
I am having an issue where my BM71 is still advertising even though the power through Vbat (PIN 14) is no longer on (removed). I'm not sure how it is still being powered on. It seems to have a voltage of around .6V on that pin at the time of advertising. Attached is an image of the schematic. Is it being powered through the Reset pin?
 
Thanks!

    Check for current flow thru Rx and/or Tx. The device will attempt to power itself thru the body diodes if power is removed from Vbatt but there is voltage on any of the input pins.
