432Hz Batch Converter - "Source" is missing for bits per sample on lossless formats (WAV and FLAC)

Simply put, there's no "Source" option listed for the bits per sample when the format is set to WAV or FLAC.

By contrast, the any of the lossy formats (AAC/M4A, MP3, OGG vorbis, Opus)  have a "Source" option listed for bitrate.
