I actually figured out what was causing it. Turns out this is a good test case for the short code and the plugin in general.
Due to the way the theme on this site is set up, each "page" is not displayed as an honest-to-goodness page. Instead, they are all gathered into a single page and navigated via anchor tags. As a result, having the "enable" button checked for a particular page did not cause it to show up on that page since it was only being referenced via hashtag instead of its own url. I was forced to insert the short code to enable it. Oddly enough, what this did was enable the reviews for every page that came after it (including the link to the blog and all its posts).
Removing the short code fixed my problem... but now I am stuck with no review form! I have not been allotted much in the way of man hours on this project, so I will edit the theme function which builds the site when and if I get a chance to do so, and see if I can get it working, but no guarantees.
In the meantime, I encourage the plugin author (or any other bug enthusiasts) to get "Glider" from Elegant Themes and test this out. I've had to make some structural changes to my theme, but I think this particular functionality may still be an issue in the original.
