Cumulus Support

I have added the Saratoga World Base Templates together with the CumulusMX plugin to a CumulusMX system running on a Raspberry Pi. The station and report units of measure settings for wind are set to mph. Trend and NOAA reports are accurartely reflecting this setting. However, on the dashboard "Todays" wind average and gust speeds are incorrectly displayed in km/h whilst the month gust value is correctly showing in mph. Is this by design or is it a bug? If a bug could anyone direct me to the coding where "Todays" wind readings can be corrected to show mph.
