Available times reflect my calendar and not the services availability

Hello! 

I have created a booking for a service. It is a self-serve service which does not require any employees. Customers can come to the store and use our service. I am the administrator, and have ensured to set custom hours under Booking page/Default scheduling policy, and yet when you go to view the customer link to book, it is showing availability for that service based on my calendar.

So for example, there should be 30 min time slots available all day on Monday starting at 10 am until 6 pm, but the first available time slot is at 10:15 am after a meeting I have that goes from 10-10:15am. And so each time slot is now on 15 or 45 mins after the hour. And any other meeting I have booked is not available for this service - in the example below, there is no availability between 4:15 and 5 because I am in a meeting: 

How do I de-link my calendar from the service I have set up?

Thanks
