Hi Chris and welcome to the forums!
Sorry for the trouble here with filtering events. Quick question: is the issue on the front end or the back end of your site? I tried searching for events on your site using the datepicker and everything seemed to be working smoothly. Perhaps you solved the issue on your own? Or maybe I’m looking in the wrong place and you can point me in the right direction. Either way, please let me know and we can go from there.
Thanks!
Geoff
