The issue is in the file: http://outfisher.out-fit.net/p7synergy/custom.css on line 282.
The style definition for:
ul li span {
has a float:right
That is throwing off the editor because it is displayed as a span inside of list tags. The solution is to probably use a spacific class name when setting the styles for the accordion you are trying to adjust with that css code instead of styling all ul elements.
