Measure being stretched to fit the whole page
I've been working on Wie schön leuchtet der Morgenstern BWV 1 among other scores and in that score, I've noticed that some measures are getting stretched out to fit the whole page, whereas most pages have 2 measures. Measures that are getting stretched here are measures 27 and 52 and I'm sure there will be more that get stretched as I get further along in the piece. But why are these 2 measures getting stretched out to page width while the other measures are 2 to a page? It can't be the note density in the measure, right, cause that's too similar in the places where I get a very stretched measure to make a difference I think, And I don't think a lyric melisma would cause it either, cause I have a bunch of melismas in the measures that are not as stretched.
But if it's not the note density or the lyric melismas, what is it that's causing the stretch and is there a way to make this more even?
