The reason why your aircraft is not being quoted from the new home base is probably because it is still in the old home base in the aircraft's schedule.
We can only help you change the home base, but we cannot make changes to your schedule data as that could go very wrong since we don't know exactly where your aircraft is at any point in time.
Should you have an automatic schedule update with Avinode, we will reflect what ever you have scheduled in your FMS.
Should you have a manual schedule, this will require you actively move the aircraft to the current position by creating a manual positioning leg.
Should you need any help on how to create an activity in the manual schedule, please have a look at this article:
