I must have inadvertently changed some configuration parameter without knowing it.

I can't adjust the gain line on my audio anymore. I used to be able to right-click the gain and "Add Point", and now I get nothing when I right click.

I used to be able to press the "Touch" gear on the audio track and the volume slider would then provide live adjustments to different points on the track.

Now the slider does nothing but adjust the track volume.

Does anyone know what I bumped?

Thanks for your time.
