MacBook Pro late 2016 three finger drag issue

Not sure if this is a general problem with MacBook Pro late 2016 or just my machine is having this problem. Try to enable three finger drag on it and do a 3 finger drag gesture on bottom left of the trackpad, there are 40% chance that it's wrongly detected as secondary click. Sometimes it failed to detect 3 finger drag at the middle of the trackpad as well.. this is really annoying as this is one of the most used gesture on a computer...
