Problem with Appointments+

I recently added a change that was made to appointments+. It removed the payment button. So, now the customer just clicks to confirm their appointment and they are directed to the payment page. We offer free estimates and when an appointment if booked it directs the person to PayPal for payment. If they hit cancel it puts the appointment in pending status and is very confusing for the client.

What I want because it's free it should not go to payment page. And the appointment should not go to pending because no payment is required. How can I achieve this?
