iCloud Space Missing

Hi All,

I'm at my wit's end with iCloud.

First, my Specs:

20GB iCloud Storage Plan

64GB AT&T iPhone 6+

When I enter settings, the iCloud page reads that I have 20GB or storage, and 10.4GB have been used. When I enter the Storage page, it reads that I have used 10.4GB. Everything seems okay. Then when I enter the Manage Storage page, it reads that I am using the following data:

33.7MB for Documents and Data

7.8MB for Mail.

Nowhere near the 10.4GB I am supposedly using.

Now, when I open iCloud using a web browser (icloud.com), the settings page tells me that I am using this 10.4GB of space for backups. I cannot see these backups on either my iPhone, iPad mini, or the iCloud for Windows app. Using the windows app, when I open the backups tab, it tells me that my backups are 0kb in size - while also telling me (on the graphic progress-bar) that I am using 10.4GB in space.

I really have no idea what to do at this point. The only thing I can figure is that iCloud tried to back up my devices a few times, failed, and then never registered the backup - yet the space is still being used for some kind of incomplete or corrupted file that I cannot access/delete.
