Chrome - Multiple Chrome icon at the taskbar

Problem

When I am fixing my laptop, I messed up with the Chrome Person setting. 

Although Chrome shows only 1 users, it will pop up an addition icon at the task bar whenever I clicked on the pinned Chrome icon (see below)

The previous behavior is only one Chrome icon at the task bar (see below)

Solution

Remove "C:\Users\YOUR_USERNAME\AppData\Local\Google\Chrome\User Data" and restart Chrome will fix the issue.
