Bug wih Global read automation ?

Global Read Automation on/off: CTRL+F12
 
This keyboard shortcut should toggle the R! of the Mix Panel of the Control Bar.
It doesn't and I think it is a bug.
 
If it's not a bug, One should see on the Control bar if this option was toggled on or off. One doesn't in the latest version of Sonar Platinum. This should be added.
