Where exactly are you seeing the two versions? A new rev of course 4698 was recently released. This new version was based on the updated version of the Groove software since the first (AE) version of the course was based on the Beta version of Groove. You should be able to see only the latest version on the Microsoftelearning.com web site unless you had already activated the previous version and are in the middle of it.
If you can give me more details, I may be better able to assist you.
