I’m sorry you’re having difficulties – that’s a strange issue!
I do see you noted having tried a few troubleshooting steps already, but can you confirm if this was still an issue with no other plugins (except for The Events Calendar/Events Calendar PRO, plus Filter Bar and WooCommerce Tickets) running and just a default, unmodified theme such as Twenty Thirteen?
If that resolves the problem can you reactivate everything else one step at a time and see if you can isolate what if anything is conflicting?
Thanks!
