Lyrics+ 2.0.0 click "Next Prepared" results in error message

[iraytrace]

With 4 lyrics prepared, I can select the first and display. If I then click "Next Prepared" it will go to the next prepared song. If I do this a second time to go to the file "05 Angels We have Heard.txt", I get the following error:

[lyrics+2.0.0.lua] Failed to call button_prop_clicked for button_prop_clicked: C:/OBS-Lyrics-2.0.0/OBS-Lyrics-2.0.0/lyrics+2.0.0.lua:1867: attempt to concatenate a nil value

If I try to directly select "05 Angels We have Heard.txt" at this point I get:
[lyrics+2.0.0.lua] Failed to call modified_callback for modified_callback: C:/OBS-Lyrics-2.0.0/OBS-Lyrics-2.0.0/lyrics+2.0.0.lua:1867: attempt to concatenate a nil value

This seems to be specific to the song in question:

05 Angels We have Heard.txt

The apostrophe in "o'er" is likely the culprit. It looks to be a stylized one, instead of the regular one.
