Structured append keeps failing. – QR Code Reader - QuickMark Barcode Scanner Review

I generated 4 QR codes with the structured append feature, and QuickMark recognizes them as connected when I scan them. Unfortunately if the combined encoded character count is 2692 characters or more, the result is an empty window with no text. If I only encode 2691, QuickMark successfully combines the data and displays the full text string.
