those sliders don't exist anymore in process version 2012
You'll need to change the process version settings of LR to version 2010 if you want to use the old sliders. However version 2012 is said to be a lot better than 2010, you better get used to it
As Guenther already told you: With PV2012, the sliders have changed there names because of changes to the underlying process of RAW development. It's an improvement, not a bug, and its absolutely intentionally!
