App+ Confirm Appointment button not submitting to Marketpress

Hi Guys

I have App+ and Marketpress integrated and running. When I add Appointment + shortcodes on a page that is not part of Marketpress products the submit does not go though to Marketpress. My shortcodes:

[app_services]
[app_monthly_schedule]
[app_login]
[app_confirmation]
[app_paypal]

This is the page in question: http://www.splide.com/cptsam/jetski-rental/
