How are you syncing the clips? Using audio sync? Is there sound on all the cameras?

Change from auto, and choose "clip" as your choice for Angles. Otherwise it will try to sync by camera.
This is meant to sync DSLR cameras. The nice part about the Angle option is that it chooses "camera" by default, so if you have 2 cameras say a Video Camera and a DSLR even though you may be syncing something like 5 clips (4DSLR and 1 Video Camera Stream) you only have 2 camera angles.
I ran into this problem when I was trying to multcam a music video shot with 2 cameras, we did multiple takes and it gave me only 2 angles, but sync'd them up. I then choose Clips and it then sync'd all 16 takes/angles.
