Target Specification Error

Hi, I’m getting some problems with OpenVAS running on Kali…

when I specify a target with multiple hosts, i.e. (10.1.1.1-10.1.1.254,10.1.2.1-10.1.2.254) the target is accepted, but if I run a CVE scan on that target I get no High, Medium or Log CVE. If I create two different targets (one per subnet) I get a lot of CVE…

What am I doing wrong?

Thanks in advance for tour help!
