APP+ not showing user's appointments with shortcode

Using the shortcode:
[app_my_appointments status="confirmed" allow_cancel="1"]

On the page broadwaybabysitters.com/account and no appointments show up for users who have them. They DO show up in the profile editor. I have also used the shortcode without anything else defined, and it still says that I don't have any appointments, when I can see on the Dashboard that I do. Fine for me, of course, but not good for my service providers and customers.

I did a quickie little screen video so you can see it in action:
