Appointments+ autorefresh="1" not working - buttons still showing

I am trying to remove the button "Show available times" on the booking page.

Basically I would like the page to autorefresh when the user selects a name from the dropdown.

My code is the following:
[app_service_providers select="Please select a teacher" service="1" empty_option="Please select a teacher" autorefresh="1" order_by="name"]

The auto refresh is not working and the button does nothing when I try and click on it.
