We've changed the way PDFs are created when you "Click for a print-friendly PDF of your survey." Radio style questions now always display the full set of options related to a particular question and indicate the one selected (if one has been selected), rather than displaying JUST the selected option. Drop down style questions continue to behave as they always have.
The aim is to produce PDF output that 1) serves better as a worksheet for data collection and 2) provides a better survey record since the option selected is displayed in relation to the options not selected.
We are in the process of converting as many questions as possible to this new format. We are leaving drop downs as is where they have a large number of options (e.g., the months of the year).
If you come across PDF output that has a problem as a result of this change, please let me know and we will fix it right away.
