appointments+ - [app_confirmation] not displaying content

I'm trying to test appoitnments+ for capability and need to get the basic concept up and running as quick as possible. I've created the demo page via the settings page but I seem to be missing the confirmation section.

This might be due to the theme I use (Enfold). I'm keen to use this product though as it seems to tick all of my boxes, just need to get this sorted.

Currently limiting me from creating the appointments. The dates in the calendar are selectable, but the times aren't.

Please let me know if there is anything you can do to help.
