Blogger makes mistakes. Sometimes a bug places 2 blog archives on your blog which makes it look bad. You have no way to remove it when you view it from the layout window.
So, here is how to do it:
1. Go to the template window and click on edit HTML
2. Find the name of the widget in the code. For eg. Blog archive 1, Blog Archive 2, Html/Java Script 1, etc.
3. Select the whole line with the coding (Make sure that you have not expanded the widget codings)
4. Now simple delete it.
5. Click on 'Save', a dialog box will appear telling you which widget you have removed.
6. Press O.K. to confirm it and you are done
