Bibles not synchronizing when linked

Yes. I get this too. Scrolling a little farther on the Bible that's ahead, will eventually sync them. 

Notice that the reference boxes show the same verse. In this way they are synchronized. But they aren't synced visually. Further, if you scroll the Bible that's behind, the other one sync's to the active Bible reference (that is it 'backs up'). This can get very annoying.
