I'm looking at the "Manage Storage" panel, (accessible from Settings > iCloud > Storage & Backup > Manage Storage) which shows a list of all the items being backed up along with a total. Or at least that's what it appears to be... the problem is that the total shown is about 50 times greater than the sum of its parts. Like this:
All the listed apps together add up to less than 60 MB, but it insists that is using (and will continue to use) 3.3 GB.
Is this normal? Is there 3.2 GB of unlisted overhead? Is anyone else experiencing this issue?
