I'll take a look, probably improperly formatted, there have been a lot of those lately. Usually the prob is that instead of all being jpg one or more files is png or something and that mucks up the works. The fix is usually to DL the file and unzip it then do a bulk edit on all the files that re-formats them all to jpg.
I just Downloaded and noticed right off the top a non-uniform file naming schema, that can cause problems too.
no two cbz readers seem to prioritize file names the same way. Thus a book that looks ok on your tablet, may be out of order on CB+ or in Cdisplay.
Broon,
going forward, you should open these books up and do some exploratory surgery, making sure all the file extensions end with .jpg
also make sure they are all named the same way ie scan-001, scan-002, etc
