Odd measure layout issue

I have a song that has, typically and appropriately, about 4 measures per line. Except two consecutive measures insist on having a full line apiece. It's totally unreadable.

The second measure has a gaping hole of staved blank space in the center 85% of the page width. This is so odd that I suspect it might be the root of the issue.

There are three instruments. It doesn't matter which combination of the three is set as visible. The image below shows a "good" line and the two problematic ones.

What might be causing this?

edit: I resolved it by cutting and re-pasting the second odd measure.
