I’d redo the multicam in this case. It looks like you’ve only got 2 actual cameras, but an angle for each clip. What you’re seeing is what is available at the playhead position in the multi viewer, and what is available in the particular angle of video being monitored in the timeline.
So the way I’d set that up:
1. In the browser, select all of the Cam 1 clips
2. Go to the Info tab of the Inspector, set it to General or Extended view (at the bottom left of the pane), and put ‘Cam 1’ in the Camera Angle field
3. Repeat these two steps for Cam 2, Cam 3, etc. If you’ve got external audio recorded, add one for Sync Audio too.
4. Select ALL of the camera clips (and audio if applicable) in the browser and create your new multicam clip.
This will reduce the number of angles to the number of actual cameras on the shoot, and they can all sync via audio (or TC if you’ve got that sorted out, most don’t).
