Nothing broken there. ID3 (etc.) in wav is non-standard and not something we plan to support, at least in the near future. Most people who want a lossless audio format are better served by things like FLAC, which have tag formats we support.
If File Explorer shows the information then you can usually import those columns into Opus to get the same details.
We might add support for tagged WAV files in the future, too, but it's not something that's broken, it just isn't supported.
