Multi-Camera Source Sequence Problem

I tried to use the Multi-Camera Source Sequence command to generate a multi-camera sequence with 3 one hour long clips. I specified the audio track channel for synchronization, and it was able to synchronize 2 of tracks only. I went back to my old method of synchronizing. I made a sequence and added all 3 clips in separate tracks on top of each other. I selected all 3 clips and I used the Synchronize command and that procedure did synchronize the 3 clips. Is there a bug in the Multi-Camera Source Sequence command?
