I received an e-mail from Valve just a bit ago...here it is.

Hi.
Yesterday, we reset your Medic achievements because we mistakenly believed you had hacked around the system to get them. Today we discovered a bug in our code that resulted in you being incorrectly flagged as cheating. As a result, I'm emailing you to apologize for our error, and to let you know that we've decided to award you the full set of Medic achievements.
Have fun with the Ubersaw,
Robin Walker.

I replied about the one that wasn't activated.
