I’m using Windows. The BB version is 2021.

After the song is finished and saved (in BIAB), ALL tracks in the mixer are green.
I then choose the following:
1 .WAV -> export song as audio file
2 Audio -> render song to audio track

Doing this, I end up with 3 files: (1) my BIAB file, (2) an audio file with the same name, (3) an audio file with the same name + the word “render.” In the mixer, the DRUMS track is now yellow, the rest of them remain green. The AUDIO track has become orange or dark yellow.
