Body+ keeps resetting its location

Scale keeps resetting its position to Issy-les-Moulinaux in France - tried to remove the batteries for 60s, have removed the scale from my account and then installed it again. No luck. I don‘t so much care about the location - but having french as the display language on the scale sucks a bit. Btw Mobile language is set to german, location on scale has been changed to switzerland numerous times now.
