CloudSOC is integrated with DLP Cloud and is trying to configure a ContentIQ profile, but does not see the External DLP option enabled in their ContentIQ page.

Once you enable Symantec DLP Cloud as your content inspection solution, the CloudSOC Protect app no longer supports ContentIQ profiles for policies of type Data Exposure via Securlets and File Transfer via Gatelets. Instead, you use Symantec DLP for all content-related policies. 

Once CASB has been integrated with DLP Cloud, the External DLP Risk Type wi no longer be available and will be managed through the DLP Cloud piece instead.

Use DLP to configure this profile piece instead.
