Acrobat XI issue inserting PDF

[palmsol]

User creates a PDF document and needs to insert existing PDF files into PDF document.  The first PDF insert works fine.  However, when the users inserts additional PDF documents, a few pages down,  the first PDF document is inserted again.  Not able to insert a different PDF document.
