Cannot Remove Widget from Sidebar

I have two items in my sidebar that I cannot remove. http://www.ebizschool.biz/wp/
There is a category drop down menu and a “widget?” called Private Label Rights.
I am using the ProSense Theme. The Sidebar these appear in are my adsense sidebar. I have never used php and css. However, I have been able to fix all my goof ups but it has taken tons of time and effort to figure them out. This one is impossible for me.

The Private Label Rights shows up in the “themes section” as a widget, but does not have an edit capability, so I can’t remove it. It also does not show up on the left side of the page with all the other available widgets. Just at the right with the widgets I am using.

Frankly, I have no idea how I ever created that monster.

Can someone help me with this?

I did read a post below about something like this but could not understand the procedure.
