Classic Creative Suite plugin knob error

 
As you see, Aliasfactor plugin's knob movement is abnormal. It works well to increase the value(clockwise), but if I want to decrease the value(to counterclockwise), a knob goes to the minimum value with just 1 pixel mouse movement.
I can't sure this is a common problem of SONAR user. If it does, please move this thread to other forum.
Sonitus series plugins works very well. It's not a problem of DirectX interface.
I like Sonitus plugins very much. They works very well although they are legacy plugins. I think CCC plugins would be great if it work properly.
Thank you.
