PDF export is not matching screen view Version 4.2.0.233521124

My pdf export does not match my screen view. It's like the export is ignoring my layout, specifically system breaks. I'm looking at this like a bug as I've only experienced it since the latest upgrade. Of course, operator error could be the issue.
I could upload images, if needed. The screen capture I pulled of musescore just now was too large to upload, I'll figure out how to trim it down if neccessary.
