Quizmaker 360: What does the "Show in quiz review" checkbox do?

Hello, Studio 360 users! I have a question about a Quizmaker 360 feature. Does anyone know what the "Show in quiz review" checkbox option does?

Some quick background: I have a 5-slide quiz. The first slide is just a blank introductory slide that has instructions and a hyperlink to a document. The remaining four slides are the actual questions based on the document. In the Question pane for the blank intro slide at the start, there is a checkbox called "Show in quiz review". I unchecked it, since I don't want this slide to appear when users review their answers. However, the slide still appears when you click the Review Quiz button in the results slide, even with this unchecked. I guess I was hoping to restrict this intro slide from appearing when reviewing answers, because it's not an actual question.

Am I misunderstanding what this option actually does? Does anyone have any information on what it's supposed to do? Thank you!

(Edit: I tried to attach a screenshot, but the site gives me an error message of "An unhandled lowlevel error occurred" each time I try.)
