Too Much Fuel in Wings

I needed some batteries on a plane. I went to the vertical stabilizer to have the fuel type be set to battery. I changed to Manual Fuel selection, and then changed the percentage of fuel to be 5%. I then changed the fuel type to Jet Fuel and it was reporting a weight of ~23 tons when whole plane only weighed about 14 tons total before the change. I moved the slider for the amount of fuel in the part and it then updated to the correct amount.However, if I change the amount of fuel in the part and then change the fuel type from Battery to Jet Fuel and I am given the huge number. If I nothing else is changed after the type is changed, the plane spawns on the runway with the impossibly large amount of fuel in the vertical stabilizer. It isn't just a menu glitch as I had thought.
