Sharepoint2013 Is Showing Reporting Services For 2008 Although I Had Installated Sql 2012 Addin For Sharepoint

Hi,

I had installed SharePoint 2013 in farm on windows Server 2012  and using Sql Server 2012 SP1 for database on Other Windows 2012 Server. I want to install reporting Services for SQL Server 2012 .I  followed the link http://technet.microsoft.com/en-us/library/gg426282.aspx  downloaded the Reporting service SQL Server Add in SP1 and Successfully installed on my SharePoint app server. On checking the General Application Setting Reporting Service is appeared showing "SQL Server Reporting Services (2008 and 2008 R2)", I need to install Reporting service for 2012 i installed and uninstalled add in several times but the problem still persist.
