what’s trending

Hi, I tried to implement the ‘what is trending” functionality on the home page. However, this does not work. I tried to display three categories, but what’s trending only shows one and this with errors also. What’s trending shows only one item with text and the other items only with heading. And the other categories are only shows by title of category, but stay empty after clicking. (They do not show content at all). Can you pleas explain me what i’am doing wrong?
