I installed this add-on today and am experiencing a strange issue. The drop-down is only working for two categories: one (mustards) that has normal products in it, and one (Recipes) that has subcats that then have products in them.

All of my other categories have normal products in them, just like Mustards, but the drop-down is not working. This is true in all browsers I tested in. Any ideas why?

Here is the website in question: http://tinyurl.com/39h2ran

Thanks!
