GetAccessRules for Directory reports incorrect NTFS Permissions

I've noticed that CommonObjectSecurity.GetAccessRules Method reports incorrect permissions.

Please note the code below:

var dirSecurity = System.IO.Directory.GetAccessControl(@"C:\Temp");
                //now we get all ntfs rights to a directory, we take all even the inherited ones
                var accessRules = dirSecurity.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount));
                foreach (FileSystemAccessRule item in accessRules)
                {
                    var account = item.IdentityReference.Value;
                    if (account.Contains("gd"))
                    {
                        Console.WriteLine(account);
                        var rights = item.FileSystemRights;
                        if (rights.HasFlag(System.Security.AccessControl.FileSystemRights.ListDirectory))
                            Console.WriteLine("List content");
                        if (rights.HasFlag(System.Security.AccessControl.FileSystemRights.ReadAndExecute))
                            Console.WriteLine("Has file read access");
                    }
                }

The permissions on that folder are the following. Please check the 'gd' account.

code output is the following. As you can see it reports incorrectly it has file read access.
