Hi Lisa,
Thanks for taking the time to reach out, and I’m so sorry for the trouble here! I’d be more than glad to assist you with sorting out your recurring events here. 🙂
If any of your recurring events are showing incorrect data as in your second screenshot, you can easily remove this data and begin again–simply click the small “trash can” icon to the right of the Event Series heading.
From there, you can quickly recreate your event recurrence series by setting the start and end dates for the first event in the series above, then clicking the Schedule multiple events button to re-open the event series options. Our Knowledgebase article on recurring events is the best place to get a detailed rundown of how these options work with the new UI, but I’d be glad to answer any specific questions you might have as you’re setting your events up!
I hope that helps to get you started! Thanks again, and let me know if there’s anything else I can do to assist here!
