I definitely don't see that DepArr page. Maybe it's an issue with inputting the flight plan manually? When I go to DepArr before execution its a blank screen with the departure and arrival airports at the bottom but if I try to select either of the airports on the bottom nothing happens. I can select the departure after flight plan execution and can also select arrival while airborne but not before.
