Attachment Name in View prefixed with Number

Hi

I have a view that is sorted by attachment names. The first column is the sorted attachment name and the attachment name is prefixed with a number. However, when I open the document the attachment name is not prefixed with a number. The column formula is @AttachmentName. Has anyone experinced this before?

Subject: If you create a new view, and add column with @attachmentname what do you get?
