The highlighted section of your screenshot has nothing to do with widow/orphan control. That is for controlling whether you might end up with just one line of text from a paragraph split across a page break.
The behaviour you're describing might be caused by having non-breaking spaces between all the words. Without seeing the actual problem document, however, it can be difficult for anyone to diagnose the issue. Can you attach a document to a post with some representative data (delete anything sensitive)? You do this via the paperclip symbol on the 'Go Advanced' tab at the bottom of this screen.
