Premiere CC multicam black screen after moving clips around

Hi guys,

Like title says, I had long duration footages from 3 cameras recording close to 30 minutes (split files). The problem is that they didn’t sync properly using multicam sync so I had to manually adjust all the clips.

The problem is after I did all that, the left side of the multicam window is all black and has no footages. It shows in the source monitor though

Is there anyway I can fix this?

Many thanks!
