This is normal behaviour. When you create a wav, either by saving or exporting, BIAB will put it in the same folder as the parent SGU/MGU file.

Also, when you next open the BIAB file, that wav (or mp3) will automatically be loaded in the Audio track.

Out of curiosity, did you try exporting as mp3 rather than mp4 to see if that works?
