Could someone please take a look at this linked .doc?

I need to update the TOC of the above document but when I do (f9), I loose the original TOC format. It's important to my employer to maintain the page numbers on the right hand side of the TOC... Section#,article#,pg. #.

I've been racking my brains trying to get the TOC to refresh as it was originally authored, but everything I try it just gives me page numbers.

What's the trick?
