When running tables, DataDynamic keeps the previously specified 'Table options' valid for all the following tables, unless differently specified.
So, if you're creating a new table and want to quickly get rid of the previous 'settings' you need to be in 'Table Maker' view and click on button 'Clear Selection' in the 'Table Options' menu.
This command will clear all the previously selected options, and set up DataDynamic to it's default settings.
