How to Make the White Rectangle that Represents the Paper in Paper Space Larger

Hello,

I am trying to use a title block I made as a template in a paperspace. I made the title block in the model space of a separate drawing, its origin is at 0,0. I used the WBLOCK command to make the title block into its own saved block, but when I insert it into the paperspace of the drawing that I want to use the title block in the drawing of the title block is larger than the white rectangle which represents the paper. I can insert viewports and print the drawing fine, but the drawing of my title block being larger than the white area of the paperspace bugs me. How do I make it bigger? I've attached an image of what I'm Talking about.

Using AutoCAD 2011.

Thanks.
