Hi. I done my first try with the tap zone, so maybe the bug is between my chair and my phone. I have a face name material how use a blue rectangle as background for the calendar event. I modified this by adding a tap action. I checked the debug tool for seeing zone but it appears on the left and 65% is missing. The blue rectangle stay at the right place. After that i add a new shape over an other part on the watch. Put the density to 0 and select update weather. Same thing the tap zone have a bad shape and isn't at the right place.
