Not sure what's happening in this situation, but I was working on one of my routes and needed to cut back on a few of my flights. After selecting the flights from my flight list, I selected "Close Flights" and then the screen in the attached file shows up telling the action is cancelled because I don't control the flights.
I tried it 3 times to no avail. It doesn't happen on other routes, just this one.
