Merged Clips from timeline creates 'dead' audio tracks, missing mono track
I'm using two system sound. Merged Clips have 'dead' tracks when created from a timeline.
If I select sound and picture from a timeline and create a merged clip, the merged clip has 'dead' audio tracks and a missing mono track. When the bwav polyphonic has 7 mono tracks, the Merged Clip has 13 tracks – the first 7 are 'dead' with no sound, the remaining 6 tracks have sound from the Bwav, and there is one missing mono track.
If I create the Merged Clip from the project bin, the additional tracks aren't created and the bwav audio are in the correct layout.
Sound devices 788T polyphonic, with between 3 mono to 8 mono tracks; and renders from DaVinci Resolve ProRes 422 23.976fps 1080p originating from Sony F55 with either 4 mono or no sound tracks.
