unusual lyric placement in second verse

Hey all,

I'm typesetting a hymn where the first section is (volta) repeated with different lyrics.

The way that the words are laid out across the two different lines seems odd and distracting to me --

particularly on the fourth and eighth bar.

(a) why is lilypond laying the two line out displaced from one another?

(b) is there a way to make things line up better?

Dave

Here is what's causing the problem (also attached):

\version "2.18.2"

\paper {
    top-margin = 8\mm                              %-minimum top-margin: 8mm
    top-markup-spacing.basic-distance = #6         %-dist. from bottom of top margin to the first markup/title
    markup-system-spacing.basic-distance = #5      %-dist. from header/title to first system
    top-system-spacing.basic-distance = #12        %-dist. from top margin to system in pages with no titles
    last-bottom-spacing.basic-distance = #12       %-pads music from copyright block
%    ragged-bottom = ##f
%    ragged-last-bottom = ##f
}

global = {
\key f \major

}

} \break

}
