How can I fix the collisions at the first note of bar 18? In the first picture the lyric extender runs through the stem of the dotted half note, in the second the beams of the slash voice act weird. Is there some setting somewhere I need to adjust?
I’d need to see the project itself to be able to tell you what’s actually going on here, but in the absence of that, you should find that if you create a new lyric on the same system as the extender line, you can then change the vertical position of both that new lyric and the extender line. You can then remove the extra lyric you created.
