Sharepoint AND SSRS Integration Content Types

I have the integration set up between Sharepoint and SSRS, but I follow the Add-in readme below. I do not see the Reporting Services select content types section. I can manually create each content type(Report, Builder, Datasource, etc..) but the images for then when I click Add in the list there are no images associated to the different content types.


Set Permissions and Add Reporting Services Content Types
You must assign user and group accounts to SharePoint groups or permission levels to grant site access to those users. Users who can access a site can also perform reporting tasks. For example, users with view permissions to access a site can also view reports on that site.
To complete the integration steps, you must ensure that all users who access and manage report server content on a SharePoint Web application have the appropriate permissions. You might also want to add Reporting Services content types so that users who have permission to use Report Builder can start it from the New menu. To add content types:



Open the library for which you want to add Reporting Services content types.



On the Settings menu, click Document Library Settings.



Under Content Types, click Add from existing site content types. If Content Types is not available, locate the General Settings section and click Advanced settings to allow content type management.



In the Content Types section, select Yes to allow multiple content types.



In the Select Content Types section, in Select Site content types from list, click the arrow to select Reporting Services.



In the Available Site Content Types list, click Report Builder Report, and then click Add to move the selected content type to the Content types to add list.



To add Report Model and Report Data Source content types, repeat steps 5 and 6.



When you finish selecting all the content types that you want to add, click OK.
