It's a glitch (I think) in the Novel Template I used for my story.
It's Easily fixed in the Scene List section of the Story Guide (the All Topics version), by unchecking the Character Information items on the bottom of Scene 6 for IC (Sargassoplasm) --I believe they were accidentally checked in the Novel template, and then checking the same for whoever you've cast as your antagonist.
It then becomes a story structure question: Is the title of the templates chapter correct, or are the character checkboxes correct? It is, I suspect the former. You can fix either one in the Scene List section as you please.
I love this program.
