Can't delete backups from iCloud (WhatsApp, Day One)

I have erased my iPhone 4S, not a single app in there, and after going into iCloud/Storage&Backup/ManageStorage I can't seem to delete the backups from WhatsApp, Day One, Pages and Passbook.

After downloading WhatsApp, in chat backup, it seems to be going on forever and the percentage is not advancing.

I downloaded, Day One again and is not detecting the back up from iCloud.

Also, going into www.icloud.com when selecting Pages, it automatically logs me out, and in my Mac, under iCloud, the backups from WhatsApp, Day One, Pages and Passbook don't appear.

Can't seem to find a workaround, any thoughts??
