Hi Leigh Basso,
To recreate the issue you mentioned our QA team used twenty sixteen with WP 4.7.4. Then installed PR 2.0.21 and created forms. Then updated to PR 3.0.1. Doing these steps did not reproduce the issue you mentioned and the forms work fine after the update. Please provide more details about your site and the plugins you are using so that we can recreate the issue and so it can be fixed. Also please let us know what are the “General Settings” in your plugin (2.0.21). You can send a screenshot of the screen for us.
