Hi Thunderthud, we tried your steps of making new volume automation nodes and deleting them, but so far could not reproduce this issue.

Silencing a part of the waveform in the Audio edit window (under the Edit menu) will automatically convert the RealTrack to an audio track and we can confirm that Edit | Undo does not change an audio track back into a RealTrack; it only undoes the silence.

Are you using a desktop or laptop computer?


Best,
Chantelle
