"Open file error" on eredear

New Here ,

Hi!

I have a tagus 2018, I've dowloaded 6 books from the kobo web and they open just fine on ADE but when I add them to my ereader, there are two books that pop the message "open file error" and it shows like they have 1/1 pages but on the computer I can read it just fine.

Any help or suggestion?!
