In the Fake sheet options you can specify the number of bars per line. By manipulating the bars per line you might be able to get the all on one line, which might help. Fake sheet doesn't affect the underlying song, so those 'empty bars must exist in the song.

I use this frequently to improve readability. If I have a section with lots of notes or lots of lyrics, I might just have 2 bars on a staff, but a long phrase with no lyrics might be as high as eight bears per line.
