I have recently installed the Appointments plugin, and set

I have recently installed the Appointments plugin, and set it up with one provider, his schedule and services. The appointment page did not automatically generate, so I built one with the short codes
[app_schedule title="Provider's schedule from START to END" worker_id="3"]
[app_services]
[app_confirmation]
[app_paypal]
I am not able to click on any of the appointment fields, cannot see anything about confirmation or PayPal. How do I make this functional? I have already uninstalled/re-installed the plugin.

Thank you.
