Scrivener shows inconsistent character spacing after importing document from Word

I’m getting different paragraph spacing for different paragraphs, despite having run Convert to Default Formatting. The paragraphs appear to have identical styles. How can I change this so the characters don’t run together? It looks like there’s too little spacing between characters, even though both are Palatino 12. (See attachments.)

That looks like a kerning issue - one is clearly kerned tighter than the other. Do/did you make such changes in Word?
