Missing command for setting significant digits in pvbatch and in pvserver the related button has no effect

Hello Everyone,
I’m using paraview in the client/server configuration with pvserver.
When I create a new spreadsheet view and set a bigger number of significant digits I then find that this has no effect on the exported csv data, it has only the default 6 significant digits.
Also I need to do this with a pvbatch job, but the command to decide the number of digits does not appear in the tracing mode.
Thank you!
