Hi Melissa,
First off, I’m stoked to hear you’re looking into PRO and I hope that will be a great fit for your site!
I do want to note that one of the perks of a PRO license is access to premium support here in these forums. We hit these forums throughout the week and generally hit any and all threads within 24 hours during the business week.
Without the license, however, I’m afraid you will need to post to the WordPress.org forum instead. We provide support there as well and generally hit those on Wednesdays. We’d be happy to help you there!
In the meantime, I know I have seen conflicts in the past with Divi when attempting to use theme shortcodes in the event post editor. If that’s the case here as well, then you can likely resolve the issue by removing those shortcodes.
Do you have any pre-sales questions about PRO’s features that I can help answer? If so, please do let me know and I’d be happy to help. 🙂
Thanks!
Geoff
