Odd vertical spacing of lyrics

[Mike Solomon]

Hey all,

The following snippet is giving me the attached output w/ the soprano line 
shifted way up after the line break.  Is there any way to get the soprano 
correctly aligned (w/o changing the distance between systems - this minimal 
example approximates a larger one w/ many systems over several pages).
