Rich,
On mine I don't have the duplicated "LE" like in your image. On my Fuel Page the labels are left to right, "Wing, LE, Tip, Center".
With the Wing Fuel Switch on the fuel burns from the "LE" column, but the total gallons match the total gallons for the Wing Tanks on the MSFS drop down GUI Fuel Page.

If the labels "Wing" & "LE" were swapped, then the fuel being burned would match both the Fuel Switch condition and the total gallons on the drop down and cockpit fuel page would match.
