incorrect license GPL is detected

OS: windows 7 64 bit
I've updated my scancode to the latest version available.
file : README.txt

scancode output :

Path                                    What    Start Line  End Line        Info
C:/doc/temporary/issue_files/README License      28 28      GPL 2.0 

In the README file attached there is license text which says BSD Unix, and not under the GNU General Public License (GPL). in the line 28. This means the correct license is BSD but no GPL

@JonoYang I am reopening as this is missing a test
