"XPATH RULE TEMPLATE" is not visible in SonarQube 7.6

I am using SonarQube 7.6
sonarScanner 3.3
I am trying to achive xpath using SSLR toolkit in sonarQube.
My xpath exprission working well in SSLR tool kit,When I further put this exprission in SonarQube rules it is not working.I understood from documents that we have to select “XPATH RULE TEMPLATE”,But it is not visible in templates.

Tried installing SSLR plugin and placed in SonarQubeBasePath/extensions but still it is not showing “XPATH RULE TEMPLATE” is not visible in SonarQube.
Can any one help?
