Continuous drawing with paint brush/pencil tool.

I just updated to Adobe Animate 2018 and when I used the paint brush tool but when I lifted my pen from my tablet it still continued to draw. I then tried the pencil tool but the same thing happened. This only happened with the pencil tool when I used Animate 2015. I would downgrade to 2015 but I want the camera tool.

I have tried restarting my tablet drivers, restarting Adobe Animate, restarting my PC and closing all high CPU usage apps to see if lag was the problem.
