Duplicate Pending Reviews

Hello. Been using your plugin for 5+ years, never a problem. Now, after migrating our site to a new server and theme, we seem to be getting duplicate reviews- like A LOT! 20 reviews to be exact. I thought it was possibly the customer’s browser cache that may have been causing it, but it’s happening to all cusotmers and even a test I just made on our site. What is causing the 20x duplicated reviews?
