Hi George!
Thanks for getting in touch with us!
We apologize for a bit of delay in getting back to you. We are dealing with a high volume of threads at the moment and we are slowly getting back to normal response times.
I believe that is a conflict with your theme’s header. As you can see, the datepicker gets hidden underneath. You can confirm it’s a theme issue by switching to a default theme (like twenty seventeen) and see if it works correctly.
As a workaround, I’ve been able to prevent the issue in your site with a custom CSS snippet. Try pasting the following CSS code into your theme’s styles.css file or using the WordPress Customizer (WP Admin > Appearance > Customize > Additional CSS):
.datepicker-dropdown {
z-index: 1000 !important;
}
I hope that helps. 🙂
Best,
Victor
