KWGT - button active area

I'm pretty new to kwgt. It's really nice, but now I've encountered the problem with touch actions. In editor all buttons work just fine. When I press button it comes the vibration response and possibility of editing event. But in widget itself, it doesn't work correctly. Only narrow strip is acting like the touch map, not whole button. Is any chance to solve this issue? Thx.
