Weird checkboxes

I have problem with checkboxes.
Different versions of Quick PDF differently read theirs properties.

I used same PDF, same code to read same properties with versions 9.11, 9.13, 9.16 and 10.14.
Result are not the same.

Does anyone know anything about that?

PDF and files are on link:
https://drive.google.com/folderview?id=0B2k-Tu8psXwNUEZyNXFKSUd0Tnc&usp=sharing
Compare txt file to see differences.
