The unexpected border array:

14 0 obj
<< /A 16 0 R /Border [ 10 10 10 60 ] /Rect [ 411 36 565 48 ] /Subtype /Link /Type /Annot >>
endobj
According to the PDF Specification:

"In PDF 1.0, the array consists of three numbers defining the horizontal corner radius, vertical corner radius, and border width, all in default user space units. If the corner radii are 0, the border has square (not rounded) corners; if the border width is 0, no border is drawn. (See implementation note 81 in Appendix H.)

In PDF 1.1, the array may have a fourth element, an optional dash arraydefining a pattern of dashes and gaps to be used in drawing the border."

Some PDF files have an additional content added before the file header (before %PDF-1.4 for example). This additional content makes all byte offsets in the document invalid, which causes the format provider to throw an exception.

At this point, to import a similar document it should be pre-processed so the content before the version header is removed before importing it.
