"not available" indicates that you didn't compile from the git repository directly, and now I do not know how old this compliance test is. Always compile from the latest git repo, never use a version from e.g. a distro as they tend to be old and missing tests. It would be great if you can do this and reply with the new compliance output. Thanks!
