flightplan question

[Nicholasarm87]

I recently started a new game my last game crashed and I wanted to look into the flight plans of the P-3B Orion on the Live-Aegean In Flames scenario because last time I played it said a waypoint 4 and 5 were to close so I wanted to change that waypoint early but when I pressed the P-3B Orion in Mission editor and clicked update flightplan 20 flights popped up with each having empty slots some several slots what does the empty slot mean? and when I go to flightplan editor for the P-#B Orion it says No data but it shows flight plans on the map so I am confused I attached the screenshots and game file
