File sort problem

[jarodsafehouse71]

Why would my most recent album additions not be sorted by filename as my previous albums? I haven't made any changes to my settings.

The albums in this category all seem to be sorted correctly: http://www.jarodsafehouse.com/mtwscrapbook/index.php?cat=39&page=1 (the screen grabs albums)

While these aren't even close: http://www.jarodsafehouse.com/mtwscrapbook/index.php?cat=8&page=2 (again, it's the screen grabs albums)

Why would it be so different ?? I use the "sort my pictures" feature each time I finish an album but it doesn't seem to have an affect ...
