label exclusion rule did not work

(from github.com/AllenHan5)
Hello all

I am facing an issue where the label exclusion rule seemed not working. Here is my config:

Name: my_warranty
Value: my_warranty
Included Paths: http://www.mycorp.com/my-warranty/.*
Excluded Paths: http://www.mycorp.com/my-warranty/policy.html

But somehow the page, http://www.mycorp.com/my-warranty/policy.html was marked with label my_warranty.

Anything I was missing?
Thanks
Allen
