Q: ICloud Drive won't display files

Ive checked all that. Using an iPad and a iPhone. When I delete something from iBooks it removes from both. I am logged into iCloud from both devices. I have 2G of available space but can't see any of the 3G that is on the drive. i have no idea how I can get the files to appear on iCloud Drive and can't find any answers anywhere.

DDouble checked and all correct BUT I don't see anything about Drive syncing. Also not sure why it shows I'm using space but not display any of the files.
