Why are there two battery icons on FR245 watch face?

From the watch face options, I have selected the first watch face, but it shows two battery icons?  One I have added from the data options as it shows the battery as a percentage (this icon is in white), but underneath the 'seconds' data there is another battery icon (this icon is in green).  Not sure why there are two battery icons?  Does anyone else have two and if so, how do you remove the green one, as I can't see an option to remove it?
