Lirics in repeated multi-voice bar

[Jogchum Reitsma]

Hi,

In bar 8 and 9 of the attached lilypond snippet, there is a split voice, 
in a repeat block.

The text placement I get (added in the attached .pdf) is doubled, 
besides  of placing the two stanza fragments just beneath each other.
(As such, the text placement is correct, but I need to get rid of the 
doubles.)

Can anyone shed a light on what I'm doing wrong here?

reagds, Jogchum
