We have four edit stations and all of us are having issues with "Shift G" or modify audio channels. We use Sony EX media. Usually, we can modify all clips in a bin so that rather than 4 mono channels, we have 3 stereo channels. We have presets that have worked for years. We have tried creating new presets, even new projects with the same frustrating results. Totally buggy. The same preset will work one time and not the other.
