When tapping on a button with a touch monitor, it is registered as two inputs. There was an issue on win7 where touch inputs were counted as touches and clicks. This seems to be the same issue on win10 as well.

This is not a regression since it has been an issue in the past

Steps to Reproduce
  1. Open zipped project
  2. Open TouchBug level
  3. Play in Mobile Preview
  4. On the touch monitor, press the button with your finger

Result: The print on the screen shows that the number of touches is 2

Expected Result: The print on the screen shows only one touch - similar to mouse click
