I've noticed while using Productions workflow in 23.1.0, if I right click on an audio clip in a timeline that is linked to a source video in a different project from where the sequence is, and I select "Audio Channels", this brings up a "Modify Clip" screen that is blank and you can't adjust any of the settings. Going to the project that holds the source video and changing it from its "Modify>Audio" menu or selecting "Audio Channels" from a clip in the same project as the sequence works fine. It's just bugged when it comes to the "Audio Channels" option for clips working across linked projects in a Production.
