C# client write via lineprotocol multiple data items with same time stamp

1

Hello I am writing to a db using c#, the following data using lineprotocol

“temperature,location=L1 value=79.69,L2=76.07,L3=84.41,L4=68.86”
writeApi.WriteRecord(“DemoData”, orgid, WritePrecision.Ns, s);

The write goes through, but when I look at the data, I only see values for L1 - it seems that all the values get put into L1.

How can I see the other values L2,L3,L4 etc ?
The query code is from the c# client samples:
try
{
int i=0;

            var fluxTables = await influxDBClient.GetQueryApi().QueryAsync(flux, orgid);
            fluxTables.ForEach(fluxTable =>
            {
                var fluxRecords = fluxTable.Records;
                fluxRecords.ForEach(fluxRecord =>
                {
                listbox.Items.Add(i+"\t"+$"{fluxRecord.GetTime()}\t{fluxRecord.GetValue()}\t{fluxRecord.GetValueByIndex(8)}");
                i++;    
                });
            });
        }
        catch (Exception ex)
        {
            listbox.Items.Add("2=" + ex.Message+ex.StackTrace);
        }

Thanks
