Having problem with the time tab of the plug -in

Hi, thanks for purchasing our product!

You need to update the booking form short code when you add it on page, and tick these checkboxes to hide them: date, week days and time range. The second step can’t be hidden or removed as the customer needs to choose a time slot to book an appointment.
