Use the CaseReportStatus enum instead of HealthRiskId when filtering on success and error

            public Func<CaseReportForListing, bool> FilterPredicate
            {
                get
                {
                    switch (Filter?.ToLower())
                    {
                        case "success":
                            return _ => _.HealthRiskId != HealthRiskId.NotSet && _.HealthRisk != "Unknown";
                        case "error":
                            return _ => _.HealthRiskId == HealthRiskId.NotSet || _.HealthRisk == "Unknown";
                        case "unknownSender":
                            return _ => _.DataCollectorId == DataCollectorId.NotSet || _.DataCollectorDisplayName == "Unknown";
                        case "all":
                        default:
                            return _ => true;
                    }
                }
            }

And add download parameters to the request when sending from frontend.

        public class DownloadParameters
        {
            public string Format { get; set; }
            public string Filter { get; set; }
            public string SortBy { get; set; }
            public string Order { get; set; }
       }
