not displaying excerpts correctly

Hi I am using the mantra theme and I just updated this plug-in. http://arewecrazyorwhat.net/ I had this plug-in set to display excerpts and it was working great but now (after the update) when the excerpt box is checked it displays the pictures from the various pages. I would really like it back the way it was. I do not have the thumbnail box checked. Are there any fixes for this?
