Removing Categories and Archives From Side Bar

I’m using the iNove 1.2.3 theme for a blog. I want to remove the archives and the categories from the sidebar but can’t find a way to do it. When I look at the side bar widgets the categories and archives widgets aren’t listed in the sidebar but when I view the actual blog there they are. Can anyone help? Here is the blog address https://boobluv.com (WARNING-It’s an adult blog). You can see how the archives and categories look out of place on the bottom of the sidebar.
Any help would be greatly appreciated.
