Eon Eon IV pdf missing the cover page

[Yahuna]

Hi,

I have realized that most of the Eon IV pdfs I own are missing the cover page. Is that normal? and if so, why?

The Grundbok and Damarian books dont have covers in the PDF, Strid and magi do. Not sure why.

Exactly, those two and others, like Troll & vättar, which does not have the back cover neither.
It is annoying, I am sure there is a reason, but annoying nevertheless.
