The DSS API is returning wrong values in ISINs Codes

I'm using DSS API dlls to fetch RIC Codes by ISINs and I realized that some RICs are wrong.
ISINs:
'BRBMEFBGI5P9', 'BRBMEFBGI5L8', 'BRBMEFBGI5F0'

Result from API:

When I make a search the site using BRBMEFBGI5L8 ISIN code, it doesn't retrieve any row:

That's my code:

var ExtractionsContext = ContextHelper.CreateExtractionsContext();

            var identifier = new InstrumentIdentifier
            {
                Identifier = "BRBMEFBGI5P9",
                IdentifierType = IdentifierType.Isin
            };

            var identifier2 = new InstrumentIdentifier
            {
                Identifier = "BRBMEFBGI5L8",
                IdentifierType = IdentifierType.Isin
            };
            var identifier3 = new InstrumentIdentifier
            {
                Identifier = "BRBMEFBGI5F0",
                IdentifierType = IdentifierType.Isin
            };

            var identifierLIst = new DssCollection<InstrumentIdentifier>();
            identifierLIst.Add(identifier);
            identifierLIst.Add(identifier2);
            identifierLIst.Add(identifier3);

            var extractionRequest = new TermsAndConditionsExtractionRequest
            {
                IdentifierList = InstrumentIdentifierList.Create(identifierLIst, null, false),
                ContentFieldNames = new[] { "RIC" }
            };

            var extractedRows = ExtractionsContext.Extract(extractionRequest).ToArray();

Could you please check it?
