It looks like the recent marketplace update broke the product links on the marketplace reporting page. The URLs for products are case sensitive and lower case. The links are trying to link to a product with a CamelCase product type. In other words, the reporting page is using "GameAddon" for part of the url and the marketplace page will only be found if "gameaddon" is used. I would have put this in the marketplace feedback thread , but it is locked.
