I've been following this thread because it's reminiscent of an issue I had
years ago with large .wav files. Something to consider: a standard .wav
file has a size limit of 2gb, and BWF files have a standard file size of
4gb. With anything larger than 4gb, the file structure changes to RF64
<https://en.wikipedia.org/wiki/RF64>. You didn't mention the file size
explicitly, but if you are missing metadata, this might be the cause. Have
you activated the RF64 support in WaveLab's audio files preferences?
