Does this happen if you enter the lyric in the lyric window, and use click-assign?

Yes. It happens regardless of weather I use the lyric window or type directly onto the score.

In that case, I would try copying the score into a new document. The corruption may be left behind. What is the source of the doc? Did you enter it from scratch, was it a scan, etc.?

You could also try exporting it as an XML, and then importing it.

I tried copying but the corruption copied too. (The pictured version is the copy!) I started over and reentered the whole song so I have a good copy. But still, it's a weird thing that it does this.

Then try the XML export/import solution. That is probably your best bet now.

I have had the same problem with Fin25/Win7

I already tried the XML import/export to no avail. The connection between the lyrics and the notes stuck.  

The lyrics seem to be connected with whichever Lyric section (Verse, Chorus, or section) they were connected with.  

So I deleted the lyrics from Lyric: [Verse] [ 1 ] 

and the extra copies of the word went away.  

I assigned the lyrics to Lyric: [Verse] [ 2 ] 

and click-assigned them in place. No problem. 

Whether there is corruption in the file or not, I do not know.

At least this is a reasonable work-around to me, as I don't really want to re-edit the specialty markings in a new version of the score. 

And I am *not* adding lyrics until I have all my parts notated in the future.

Hope this lends some assistance to anyone else that this might happen to. 

Lyrics should be the last thing you do.

Mike Rosen, I hear you on that, but often I NEED to have the lyrics in the score. There are many reasons for this; the piano/vocal was created first, the choral arrangement was written before me (the orchestrator) got to it, or simply to keep my place in the score while I work.

When the lyrics get assigned strangely like this (I have seen pretty much this exact bug many times) I have to select the measures that have the wrong assignments and Clear Selected Items. Once I had some mirrors in there that I had never created, and converting the mirrors kept the problem from reoccurring.

It has been my experience that lyrics are able to spread the measure but unable to move measures to the next line.  Your first measure obviously spread for the lyrics, but there is no way the lyrics will fit in the 2nd measure without moving the 3rd measure down a line, so the lyrics stack up.  If you select that last measure (mm 3) of the first line and (down arrow on windows) move it down to the next line, the lyrics should clean up nicely.  Does that help?

I use Finale 25 with Windows 10: When I switched to Scroll View, my Lyric Click Assignment worked like a charm.  But it wouldn't work at all in Page View, for some reason, and I was using the new Finale 25 templates, too, as far as I know.
