Where has the disk space gone?

Mine is also the 64 bit Professional Alan.

This is how mine is setup:

   
   

So I read it that it should delete old backups beyond the W7 designated amount. But it didn't do that and I had used about 1.25 TB of that 400GB is the System Image and the rest 750GB was multiple backups.

I could set it to just have the System Image. But I need the backups and don't mind the multiples beyond the size specified now I know how to delete excess.
