Region List reload failure

I use Steinberg Cubase Pro 8 with some of CMC controllers from some time. What I noticed is that the region list of the event that i’m working with, stays there after i switch to the next track with one of CMC CH controller buttons, or mouse click, or even arrow keys on keyboard (audio graph automatically switches to next event, which is intuitive). When i click with the mouse to that region list (which doesn’t correspond to currently selected track), it goes blank. To load the region list that correspond to the event that I want to work with I always have to close and open Sample Editor with “Enter” key on keyboard.

Has anyone noticed a similar problem?
