WooCommerce Bookings Products Spinning

So I have two sites that use Woocommerce Bookings to create product availability calendars. Both sites have now had recurring issues with the calendars spinning and not providing available dates. I believe this is a caching issue, since the problem resolves once I clear the WP Fastest Cache, as well as our Sucuri Firewall cache. Could you offer any insight as to how to avoid this problem? As far as I know, caching isn’t even supposed to hit Woocommerce products, so it is a very confusing problem.

For the link above, we had the issue this morning, but a customer reached out to me and told me, so I had to clear cache for them. My incognito window now shows no blue spinning. I can provide you with more product links in a private reply, so I can try to supply you with one that isn’t working as soon as possible.

I have spoken with Woocommerce Support and Sucuri about this problem as well, and will continue to reach out to all of you for help in diagnosing and solving this problem. It is incredibly frustrating and losing sales.

Best,
David
