Clicking the Default button will reset any options you have set (including the costing feature) to the default, which is no costing enabled.
You will need to setup your costing details again in order to see any costing.
Also as an FYI, you only will see the .csv files after the file has been printed. If you want to see the costing prior to printing, you can select the option to Rip Only, then when the job status goes to holding, select the job in the queue and click on the Costing icon near the top right.
