Availability not showing correct

I cannot pin point exactly when this changed but I believe it was around the same time the interface change, which is not efficient for my application.  

I have 4 meeting options that my customers can choose from and schedule.  1 hr, 1.5 hour, 2hour, and 3hour sessions.  Previously, depending on the session length they choose, it would show my calendar availability for that length of meeting.  Now it appears that it will not show any availability for approximately 1 week out.  I need my customers to be able to schedule the next day, if I am available.   I am having to go back to manual scheduling for last minute meetings, which is very time consuming.

I love the scheduler because it saves me so much time in back and forth emails.  I have removed all limitations to time line but it does not change my availability that shows.  

Please help!
