How to Modify 787-10 ATC Call Sign for Liveries

Hello everyone,

I just upgraded to the Premium Deluxe version in order to fly the B787-10. I downloaded one of the livery packs which adds Air Canada, however whenever I use this livery the ATC airline name is ‘nor Shuttle’ and not Air Canada. On the A320neo livery for Air Canada the callsign is correct. I’m wondering if there’s a way to edit a file in the game directory to correct this, as adding ‘AIRCANADA’ as the callsign in-game mispronounces it, and adding a ‘-’ defaults back to ‘nor Shuttle’. It’s really annoying for immersion as the other livery mods I’ve downloaded all seem to use the correct air line name, whereas this one doesn’t, but I can’t seem to figure out where MSFS is pulling that information from to use on ATC.

Thank you very much!
