Backup Numbers don't add up???

[Crispykickz]

I am having this problem on my 4s running iOS 6. It seems like my cloud backup is not reporting the correct numbers. When I turn off all switches on what to backup, I am still seeing 1.5GB being included in the backup file. I have no idea where this is coming from. And yes, this is when ALL apps are shown. I have included a screenshot.

You get 5GB of free iCloud storage for:

Photos and videos in the Camera Roll
Device settings (for example: Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts)
App data
Home screen and app organization
Messages (iMessage, SMS, and MMS)
Ringtones
Visual Voicemails

You have only turned off app data and photoroll, the data must be made up from the other sync settings.
