Openscap return "no value" / server inconclusive


I’ve a weird situation in few servers, when I run an openscap job I’ve as a result a “no value” into the behaviours of “Ensure No World-Writable Files Exist”:

The servers are configured as the same of the others, no difference.
It’s not a real problem but the server is still in “inconclusive” state (the orange one) and I have no remediation to do.

If it’s useful the rule ID is xccdf_org.ssgproject.content_rule_file_permissions_unauthorized_world_writable
and the policy is the Standard System Security Profile for Red Hat Enterprise Linux 7 and SELinux is disabled.

Expected outcome:

something to fix
