Page numbers being lost on unformat

Running BS8 with Word 2007, Chicago 15th A, I am shooting temporary citations to footnote and then adding page references thus: [Delio, 2008 @44 #1494]. Decided to format to see how I was going, then unformatted - now all the page references eg: @44 have been stripped off - even if I format again. For now I am adding page references outside the citation ie: [Delio, 2008 #1494], 44 - but surely these things should stay put on format-unformat?

I cannot reproduce the bug

I cannot reproduce the bug with Word 2007 and Biblioscape 8. Please create a simple test document with the sample database and email me the files before and after the formatting. Thanks, Paul
