Adobe 6.0 Pro--PDFs created from multiple PDFs don't have bookmarks from structure?

Question

I'm working with my company's 6.0 Pro (old, I know, but what we've got is what we've got,) on a Windows 7 machine. I've read online that in 6.0, PDFs created from multiple PDFs, by defaut, should have bookmarks from structure that use the original filenames as the bookmark names. I was surprised to read this, because ironically enough this is precisely what I began looking online to see if I could do, and all I could seem to find then were ways to get rid of that function. I don't believe that our installation has been modified in any way, but the binders I'm creating don't automatically have bookmarks from their structure, nor do the bookmarks I'm creating from the structure by menu command have the original file names as their names. Such an automatic bookmark structure w/ that naming scheme would in fact be very helpful in our workflow, as we deal with large volumes of files where outside data paired with file names needs to be one-to-one matched against the actual pdf contents, and opening files individually is time consuming. As of now, when I go to create bookmarks from structure in my document made of multiple pdfs, I have two choices: "Document", which only creates a bookmark to the first page of the whole thing, and "Part," which creates bookmarks to the first pages of all the documents that were combined, with each bookmark named "Part."
We would be satisfied with nameless bookmarks except that the combine feaure is also unreliable. It usually switches the first and last files of the alphabetical order, but not always, meaning that we can't rely on bookmark order to know which file we are looking at once the binder is created.
What I'm hoping to discover is if this behavior for 6.0 Pro is really abnormal and if so, what fixes or workarounds might be available. Thanks.

Just to clarify --
"... should have bookmarks from structure ..."
Not true.
If a PDF is tagged then Acrobat Pro can create new Bookmarks from the PDF's structure (from the Bookmark panel's Options menu).
Currently there is no other mechanism for this.
This may change after PDF-2 (ISO 32000-2) is released but that is still out on the timeline.
Just some things to consider.
When combining multiple PDFs into a new, single PDF click on the Options button and tick "Always add bookmarks..."
This should give you the filename. If a PDF has an entry in its "Title" this will be a bookmark nested under the top (filename) bookmark.
Also, when combining PDFs if there is no entry in "Tiltle" expect to see the filename as a bookmark.
It there is an entry for "Title" expect to see the "Title" entry as the bookmark.
What you describe for the elements/tags "Document" and "Part" are consistent with what they are and how they are permitted to be used in a tagged PDF.
(See ISO 32000-1, Section 14.8)
