I'm convinced there's some kind of bug in multicamera editing. I'm going along and all of a sudden, in multicamera track mode, it's showing 20.06 seconds out of sync, but it's clearly still IN sync according to the waveform, and when I unmute and listen with the secondary audio track. Then when I expand out to multiple tracks, the 20.06 disappears. Why does this happen?

Multicamera track (shows out of sync)

Expanded to multiple tracks (shows in sync)

Oddly enough, when I make the next camera cut, the out of sync indicator disappears (while in the multicamera track) I don't understand this at all.
