Hello;Already installed several Grafik T devices on this project, having issues when they are ganged.First issue the dimension, pretty tight installation, too deep too wide even for a deep box when you need to accommodate all switch legs, travelers, neutrals, etc.Second issue, always when ganged, the plate seems not to fit correctly so the dimmer/switch do not work properly, some times gets stuck on the On position, won't dim/off the lamp, pressing the plate near the buttons make the dimmer/switch operate. Those are not expected behaviors for such expensive products.Has anyone experienced the same or similar problems...???
