Bookings allowing appointments during busy time on calendar

Hello,

Bookings in allowing appointments to be scheduled when my time is marked as busy on my calendar.  In settings, I'm the only staff person, and when I look at 'Calendar & Availability' I see my calendar and all the current appointments on it.  However, when I go to a particular service, on which I am the only Staff assigned, and look at 'Calendar & Availability' it shows as wide open...  How do I get the Service to recognize that I'm busy and not accepting appointments at those times?
