Featured Slider Can't Add over 4 Pages

Hi, I've really enjoyed using the free version of your theme and will update to the pro version if this get's ironed out. I am trying to add a 5th page to the featured page slider (it says I can add a maximum of 20) but I am only able to add up to 4. Everything works beautifully while having 4 pages or under, but when I try to add the 5th or 6th or so on and refresh the page, only 4 drop downs appear to allow me to select the featured pages. This is an image describing what I mean: https://s3.amazonaws.com/lucida-issue/Issue_Lucida.png Note the number of pages is listed as 6 but I only have 4 options to choose from. Thanks in advance!
