I set Monday through Friday work schedule to be from 8:00 to 18:30.  I have several services ranging from 30 minutes to 1.5 hours in duration with a 30 minute buffer between appointments.  When the customer attempts to book an appointment for a 1.5 hour service only 4 slots show up; 8:30-10:00, 10:30-12:00, 12:30-2:00 and 2:30-4:00.  It should show a 4:30-6:00 slot but it doesn't.  I even tried making the work schedule go from 8:00 to 19:00 but I've had times when it shows 24 hours worth of slots.  I don't know what's going on.  I've cleared browser caches, used different browers and it's not consistent.  

I've attached some images to show the problem.  If you want to see the problem live, go to treadrightmobiletire.com and click the "Schedule Service" button.  I just upgraded to the latest version hoping the problem would be fixed but it isn't.

Figured it out.  Not only did I have to change the work hours for the business but I also had to change the work hours for my one employee.  To do that, bring up the employees page in Amelia and edit each of your employees.  When you edit an employee, notice that there are tabs at the top.  Click on the "Work Hours" tab and make the appropriate changes.
