Not working when I check "or use Javascript to resize and center the popover"

The popover is not working when I check "or use Javascript to resize and center the popover". It disappears. It works if I don't have it checked. Also, when I select a style that isn't "default", it won't appear either. Here is the link:

Its currently working because I manually put in the position, but I prefer that it center it automatically.
