[Theme: Mystique] remove search and categories

(I’m assuming I am using the most recent version ass I am just using this on wordpress.com)

Anyways, if you go to my new website I am trying to set up https://phantomfrogstudios.wordpress.com/ you will see a couple widgets on the side. I looked through a bunch of themes for one I liked, and i settled on mystique, as long as I could move/delete everything from the sidebars, because I don’t want anything there. In my widget setting I have the ability to move/delete widgets from the side and bottom. Excellent…if it worked.

So i removed everything from the sides and put them on the bottom, yet the search and categories is still there no matter what. https://phantomfrogstudios.files.wordpress.com/2013/11/untitled.png
So any direction in how to solve this would be most appreciated.

thanks you.
