Armada Unit Class Limited to "Sample" I-185 Vehicle

I recently reinstalled the War Thunder CDK. Once I opened up the mission editor, I tried to create an Armada unit, but the only class available was titled “sample_i_185_m82”. Upon further inspection, I found that instead of using the “War Thunder > content > base > res > aircrafts” file, the CDK is using the “War Thunder > content > pgk_local > gameData > flightModels” location on my computer, which, of course, limits my selection of Armada classes to the “sample_i_185_m82”.

Is there any way I can fix this?

Will it corrupt my game files if I copy and paste the aircraft files directly from the “content>base>res>aircrafts” folder into the flightModels folder?
