I have reviewed the code. The CI fail of Automatus on CS8 and SLE 15 is fine because the rule isn't part of these products but it's a part of only RHEL 9. The Automatus on CS 9 reports correctly as notapplicable because this rules is a part of a group that is machine platform. But, the rule is templated and doesn't modify the template.
