Dates are not automatically updated

I have used your plugin on this website and page https://www.nandabarbervic.com/appointment/

however, the dates are not automatically updated, I have to manually clear the cache and delete it in order to get the dates updated to the current date. It is not a great experience for our customers because when they go to the website to book for the current and future date appointment the first thing they see is the past date.

This is really urgent, someone please reply soon
