Page Builder – Interfering With Watu Pro Certificate Generation

My site is built around Namaste LMS & Watu Pro for quizzes. I have run into an issue with the auto-generated certificates with Watu Pro, and have found that the Page Builder plugin is the culprit (deactivating the plugin generates the certificates correctly).

The Watu Pro author thinks its something in Page Builder’s GET variables or plugin configuration. I have crawled through the configurations and I do not see anything that might tie to this. So, is there anything I can do to try and fix this on my end?
