It looks like there is a problem with some of the details for your Classic-Craft Mahogany door in this category. In IE when I see this item listed in the results there is no information after it, there is no learn more link in the listing for this product.
This tells me that there is some value for this item that is causing the results that you are seeing. As a test you could try taking this item offline with the checkbox in the admin area. When you do this it should make it so the item does not show in the store. If you can do this and get good results for the other items it would indicate that there is an issue with this particular item.
As for the spry area have you made any modifications to this? I have not seen this before, the menu is based on the names of your categories and items. You could update the css for this in the SpryAssets/SpryAccordian.css, in here look for the style titled:
In this style the overflow is set to auto, you can update this to hidden to have it hide the overflow info. Please post back and let us know the results that you get.
