Hi Edward,
Thanks for taking the time to reach out! On reviewing your purchase history with us, it appears that these two orders are for two separate products: Events Calendar PRO, our premium calendar and events solution, and Event Tickets Plus, which adds ticket sales functionality for posts, pages, and events. If you should have any questions about either of these products or whether they might be required for your intended setup, let me know–I’d be happy to clarify further! 🙂
I hope that helps to address your concerns here! Thanks again, and let us know if you should have any other questions!
