Re: Page size goes haywire

I'm not getting any errors or warnings when compiling. When I compile this
single song by itself, the margins stay where they belong. It's only in the
context of a book with more songs that the margins go haywire, and they
stay that way until another specific song is compiled.

Here is the "wrong size" file:

https://github.com/neonscribe/lilypond-lead-sheets/blob/main/Core/Chega%20d=
e%20Saudade%20-%20Ly%20Core%20-%20D.ly

and here is the "right size" file:

on%20Moon%20-%20Ly%20Core%20-%20Bb.ly
