Booking process complete one step befpre

Hi,

When I test the booking syetem, it always complete the booking process one step earier, in the other words, in the page that customer enters their details(name, email, etc), and once click “next step” to the next step (confirmation), the booking actually is completed before the confirm step (New booking shows up in my backend, and customer receives the confirmation email).

Could you please help me to figure this out? Thank you very much!
