Issue selling aircraft, as owner is blank

Hi

My Starting Aircraft ID #3 which i purchased from the lessor upon expiry of the lease i now want to sell this aircraft but for some reason the aircraft is not owned my my airline. The owner area is blank, so it will not allow me to sell it see attached screenshot

World is: R1

Airline is: Canadian Airlines

Airline Id is: 3

If you can correct the ownership so that i'm able to sell this plane. it would be greatly appreciated.
