Export to pdf in preview

Question

I'm trying to take a bunch of png files and convert it to a pdf file, so I can have all those files in one big pdf file. But since I upgraded to Mountain Lion when I try to export all, in preview, and select the export pdf, it only exports 2 files. Is this a bug?

Answer 1

this is what I got:
