I think I have found the problem. The translation table was matching other content types (like comments) with the products and it included it as a product. Anyways, I've made a quick fix on the code, it should show only the proper elements with the language.
I will include this bugfix to the next update so you won't loose the changes if updating the plugin.Best,
