FS Flight Planner memory

When I set up a flight using FS Flight Planner and say select "High Altitude", the altitude selected is 18000 feet. If I change that to another higher setting (say 24000 feet) and then save the plan, when I return to the plan (after a reboot of my PC) on the next running of FSX, load the saved plan, the altitude setting does not come back at the previous entry for 24000 feet. What am I missing here?

Thanks

When you go to reload the flight, do you click the tab find route? If you do this it will create the flight over. Once you load the saved flight (the 1 at 24000) click the navlog tab and it should have you at FL240. Then click ok and your good to fly.
