Why is what grey, the images of the pdf info? That's just how it shows on my computer when I click on the info for the pdf document (i'm on a mac). But if you dowload the pdf, you should be able to right-click on the it, and see the info options yourself on your computer.
"Energy" as the author would be done at the document creation stage, I think (in this case, in the Libre Office program.) (I could rename the pdf document in the "pdf info" box, but not the name of the author, etc, not at that stage.)
As for the editing, I didn't edit in a pdf creator. I just downloaded libre office (a free program), which is what the original document shared with us was created with, opened the pdf from there, was able to edit EVERYTHING, including the watermark arrangement, dates, names, results, etc, and then created a new pdf after I edited it. It was that easy. There was no security on the pdf that was shared with us, which is why I was able to edit it, I guess. But like I showed, a pdf from the official site was created with Adobe Indesign and Acrobat.
