This behaviour affects songs in that have a song sequence with repeated sections, and it appears that the song sequence is being read twice, once when adding the song to the OOS and again when Previewing the song.
e.g. a song lyric is entered in the database as Verse 1, Chorus, Verse 2 and a song sequence is added as V1 C V2 C - i.e. the Chorus is to be sung after each Verse.
However, when the song is added to the OOS, the Chorus title and section is added after each Verse., so in ‘Edit Song’ the lyric appears as Verse 1, Chorus, Verse 2, Chorus.
This would be Ok if the Preview screen just showed what was in the OOS.
But the Preview Screen then follows the song sequence and displays the song section once for EACH TIME the section title (in this case ‘Chorus’) appears in the song in the OOS, i.e. it now shows the Chorus TWICE after each verse
i.e. Verse 1, Chorus, Chorus, Verse 2, Chorus, Chorus
This is also what appears in Go Live.
The song can be corrected by Editing the song in the OOS and either deleting the song sequence completely, or by deleting the repeated song section(s).
This song remains unaffected in the songs database, and the corruption does not occur when Previewing a song directly from there.
This behaviour affects any song element that is repeated in the song sequence (Verses, Bridges, etc),
