"Include last instance on pages without story text" doesn't work. Power Headers Forum

I was ecstatic to learn about the ability of this plugin. I purchased it. I didn't need it for very complex usage. I just followed all the instruction in the manual and I was able to create nice running headers wherever story text was found on the page. My only problem is that when the story text is not available on the page, I would like to have the last instance on the previous page as the header. I selected this option and tried to fiddle around to get it to work, but couldn't get success. Can anyone help me to resolve this issue?
