Need Help with "Array_" showing up under product listings

:dontgetit**Help** im having an issue with my product listing display. when I click on my product main category it doesnt show me only the product on that category, it shows me product from all the rest of the categories. Dont know why its doing this.:dontgetit

Here is an example:

http://www.aztecasoccer.com/index.php?main_page=index&cPath=1
if you click on Apparel, or Footwear other product shows under the listings and when you hovering the mouse on the product in the url it shows: product_info&cPath=Array_16_41_42&products_id=162

your help would be greatly appreciated, btw im using zen cart 1.3.9h

This isn't normal Zen Cart behaviour so must be related to some change. What add-in mods or custom developments are you using?
