[Plugin: Single Post Template] Bug? 3.1.2. not functioning.. :(

I get the meta box and am able to set the template. But then I go to view the page output and it didn’t use the template ??

I modeled the template after the One column, no sidebar template provided with Twenty Ten for pages. I made the specified header alteration. But it won’t stick. Any thoughts?

Note: When I apply the page provided by Twenty Ten, it sticks to pages I apply the template too; which is obviously the out the box behavior. So I though the post version might look the same, but it doesn’t even render.
