Default Track sounds?

[BNSFdude]

Hi all, as I've been working on the new truck sounds for the 40 series update, I noticed that only the trailing units actually abide by the choice of bogie audio as per direction in the locomotives' bin files, but the lead locomotive opts to use the default awful sounds. Has this been addressed before, and if so, how can I fix this? I do not wish to release the set if it's simply a QA problem on my end and I did something wrong.

I believe the problem is that the locomotive with crew members has a line for the bogie sounds that is something similar to "RSC\SD40BnPack02\Audio\RailNetwork\Bogies\BG_Modern" instead of "MLWAudio\16-645E3\Audio\40 Series\SD_Boguie"; you may want to re-inspect the bin file of the locomotive.
