It has come to my attention that Dataviewer changed a few of the parameter names upon exporting a .log file to a csv. Not sure if this is permanent, or only involves specific tools. Also not sure if this is due to the dataviewer version, or.... what.
In any event, please update to the latest version, DSLogredux 2011, Ver. 10.1.0.
It is available here:

and REMEMBER, donations are ALWAYS appreciated (shameless, I know), but... HEY.
