How did I get this flight scheduled 8 days in advance?

I’ve been modifying the schedule of one of my planes a few times, using the +3 days delay when activating it, but this one (see attachment) seems to have added three times that delay (are 9 days delay possible?)

Thank you

This has also happened to me, I would get new flights added 7+ days away each day on 3 aircraft, it stopped once I added a new flight to the schedules and activated it.

nothing to worry about. ghat happens sometimes. flights only get booked three days ahead thou so those flights simply stay in there until their time has come
