2nd Verse lyrics drop below all staves, alignBelowContext not working

[Keizen Li Qian]

Hi, everyone, I'd like help getting 2nd and 3rd verses to align in the assigned staves rather than dropping to the bottom. I've attached the files and choralpart.ly is the file to compile. 

In summary, the construct I am using is:

\new Lyrics = "firstVerse" \lyricsto "tenors" \lyricmode {
      not repeated text
                        <<
                        { first verse }
        \new Lyrics = "secondVerse"
                \with { alignBelowContext = #"firstVerse" }
        {
                \set associatedVoice = "tenors"
                        second verse
        }
        >>

not repeated text

}

Any help is greatly appreciated.
