Q:

If you sent an in-game report, you will garner no response as indicated on the Bug Report window.
I believe there is no way for the CS Team to remove achievement progress. Your only choice would be to start a new account. You can, however, move other achievements into the progress window, and leave them there. There will always be 3 achievements-in-progress showing.
Good luck.
