It's hardly surprising you're not getting the correct footer content. You've deleted the code that inserts it.

As for your barcodes, if they're being inserted into the header/footer via a bookmark cross-reference, and all the source documents use the same bookmark, only one of each bookmark will survive and all the cross-references will point to that. The workaround would be to apply a unique Style name to the barcode pairs in the document body (i.e. one Style for the customer ID, and another Style for the document ID), then use two StyleRef fieldd in the header/footer, referencing those Styles.
