ATC Menu Population & AP controls

Hi All,
I have done a search and as yet not sure if this is a bug or whether or not it's something that I haven't stumbled across as yet, so thought why not post it up.
During the flight all the instructions are displayed on the ATC menu (turn left to there, go that heading at the height etc. etc.). Now when I have finished with that flight and do a different flight, i.e. a different plane in a different location I find that the new flight loads with the previous settings.
For example if I had the AutoPilot on with the headings set at whatever, the new plane at the new location retains all this information. So when I start a new flight the AutoPilot is engaged so have to hold the brake while I turn everything off and get it back to normal.
Also the ATC menu is still populated with the previous instructions that were provided on a previous flight. Anyway to clear the logs automatically when doing a different flight altogether.
Obviously I can close the application and start it again and this will clear the logs, but I would have assumed that FSX would have cleared these up when doing a different flight.
