Old review shortcodes & settings can’t be found

It’s been about a year since I first set up WP Reviews as Review Boxes to show the company’s star ratings from Yelp, Google and Trip Advisor. These Review Boxes are displayed using shortcodes such as [wp-review id="11"] Today, when I went to edit these shortcodes to adjust the stars, I can’t find them anywhere in the plugin settings. They’re not listed in the Review Box metabox. The whole interface looks different now and I don’t see any reference to these shortcodes or settings. Even ticking all Screen Options checkboxes doesn’t bring them up. Where can I find and edit these review shortcodes? Is the current plugin not compatible with previous versions of this plugin?
