Metric unit overlays?

Hi,

Just got my new Virb XE and playing around with sensors, overlays and Virb edit. I have a Tempe sensor linked up and on the Virb XE the units are set correctly and showing in degrees celcius, however when editing videos all the temperature overlays are in F?

Surely there is a way to display the temperature overlay correctly in metric as shown on the camera and the phone app? Also noticed that the same is true for all the gauges which will make this effectively useless for anyone outside the US? (i.e. all in feet and miles etc)

Please tell me I'm just being stupid and there's a simple way to switch to metric units for the G-Metrix overlays - the only reason I brought this camera,

Cheers, Andre.
