Hi wkt,
Do you mean PDF export or Excel export or OpenDocument export through the Export menu of your report?
Because you wrote .csv, I wonder how do you export your report data.
Regarding the rate process and rate success columns, please may you share what formating settings you define for your cell? I guess it is a graphical widget properties that could be not accurate, while exporting exports the values themselves is not a matter of graphical object.
Regards
J-Serge
