The sidecar is a simple text file. I just use my editor to delete all the crs tags like:
crs:Version="8.7"
crs:ProcessVersion="6.7"
crs:WhiteBalance="Daylight"
crs:AutoWhiteVersion="134348800"
crs:Temperature="5500"
crs:Tint="+10"
crs:Saturation="+5"
crs:Sharpness="25"
crs:LuminanceSmoothing="0"
crs:ColorNoiseReduction="25"
crs:VignetteAmount="0"
crs:ShadowTint="0"
crs:RedHue="0"
crs:RedSaturation="0"
crs:GreenHue="0"
crs:GreenSaturation="0"
crs:BlueHue="0"
crs:BlueSaturation="0"
crs:Vibrance="+10"
crs:HueAdjustmentRed="0"Hopefully this will also help you
