Can’t overwrite documents on Skydrive

When I make changes to the same document, Skydrive automatically creates a new version of the same document, instead of letting me overwrite it and therefore just having one document.  As a result I have about five or six versions of the same document in my Skydrive folder. This can be very confusing and annoying when I want to consult that document, as it takes me a minute or two to figure out the correct version.

There should be an ability to overwrite the same document and therefore have only one version.  That would make things so much easier.
