So I ran in to a weird problem that I thought I would share the reason for it and the solution. I had some PDFs that had form fillable fields. They were filled out by people and sent in. The problem was that the all the fields were blank unless you clicked on them, then the data was shown. After some googling I found out that if a person fills out the form on a Mac using Preview instead of the actual adobe reader, it saves it in a buggy way. The way to solve the problem is to open the file in adobe acrobat, export the data, then import it back in.
