ssrs 2008: csv export keeps putting quote qualifier around my fields

intended output of csv and how it appears in report preview:

"abc","123"

actual output of csv:

""abc"",""123""

csv render settings used:

<Extension Name="CSVNOHEADERNOQUALIFER" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering"><OverrideNames><Name Language="en-US">CSV NO HEADER (comma del)</Name></OverrideNames><Configuration><DeviceInfo><NoHeader>true</NoHeader><FieldDelimiter>,</FieldDelimiter><ExcelMode>False</ExcelMode><Qualifier></Qualifier><Encoding>ASCII</Encoding></DeviceInfo></Configuration></Extension>

My understanding is the qualifier should only be triggered if a field delimiter is present in a field.  But this is not the case.  How do I use double quotes  around my fields without the csv export wrapping it in another set of double quotes?

thanks
