Removing empty field for category page titles/intro

I started using Parabola for my new site last week. This is my first site so there’s a lot to learn, but generally it’s going pretty well. One thing that I can’y figure out is how to remove a tiny bit of empty space left behind on my category pages.

My plan is to have category pages for topic-specific blog archives. I don’t like the way that the Category page title and intro description look on the page, so I turned those off in Parabola settings, and left the text field blank on the category Page interface. This an empty box at the top of the page. If I try to accomplish the same, but use a link or category tag in the Menu’s option – avoiding the “category page with intro” settings – the top of the page is still left with a tiny, empty box.

Is there any way I can delete this entirely? I identified the item using Inspect Element on Chrome, and it suggests that it has to do with the header settings, but I couldn’t find any solution in the HTML editor. Can somebody point me in the right direction or just tell me how to fix this?

Thank you in advance for your advice!
