I'm still on 612 build of the 64 bit version of BIAB 2019, but I find that when I render a song in the wave format, it works, but it adds the file to the audio track. The next time you open the sgu, you have an audio file playing at the same time as the real tracks. It seems like a bug as it repeatedly does it, at least, in this my first 2019 song.
