problem module mod_news_pro_gk4 and problem Submenu

I have a problem: the site works perfectly I inserted a dropdown sub-menu only on certain pages, so it appears on the home page but only on certain pages. And until far so good!

But now I will explain the problem!

I put in the home page mod_news_pro_gk4 and setting a single item from the chosen category, and when I click on the article sent me on the inside clicked specific article that is part of the category to which I assigned the submenu dropdown, however, this menu is not seen.

The strange thing that the sub works fine on all pages, but only if it does not work by clicking on the article module mod_news_pro_gk4

I enclose three photos to let you know!

photo 1 (I show the form where I click to entreare titled IDEAS

photo 2 (I show you the article page where you can not see the submenu, and that I would rather that you saw)

photo 3 (I show the submenu as it appears on other pages working, and I worked also entering the modules)

please help me it is very important!

this is the photo

PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!
