So I think the main issue is that their digital archive is a completely separate part of the website. The fact that they have "Digital Archive" as a differently colored tab, might make you think you're in the archives, but no, by default you land in the catalog. And the catalog is much larger than the archive, so most of the entries in the catalog do not lead to an archive entry.
So go back to the site, click on "Digital Archive" even though you may think you're already in it. In the "Magazine Library", on page 2 (not very well indicated, again), you'll find some Playstation magazines.
