Patch Manager doesn't let me scan for Vulnerabilites

Hey all,

we subscribed for a Patch Manager license for our clients. After reactivating the Core, I was able to download all the Update Definitions. But a Security Scan for Vulnerabilities is not possible at all - and this is where I need your help.

Based on this 2 documents

it looks like the bahavior is wrong in our Patch Manager - in the documents a Security Scan is the basis to start with, but it is greyed out here (see Screenshot).

Thanks in advance

Norman
