Bookings Schedule Time Slots Not Showing in 30 Minute Increments

I am setting up a Booking with Available hours from 9am-12pm and 130pm to 4pm. The Time Increments are set to 30 minutes and the meeting time is set for 1 hour. I'd like the available times to show as 9am/930am/10am/1030am/11am/130pm/2pm/230pm/3pm. But, they are showing as 9am/10am/11am/130pm/230pm. I would think it should be smart enough to know there are hour increments available if they haven't been scheduled yet.

Does anyone have any thoughts on why it won't show increments of time on each half hour within the available times when it's set for 30 mins? Thanks in advance!
