The application will take DWG/DXF files and export them to PDF without too much settings or configured. It's impossible to make adjustments before conversion from within the application which means you will have to somehow edit the DWG files. There is no option available on the application to allow you to select only a certain number of elements. Check the DWG file and make sure that the table is properly defined and attached to the other elements. Link one element to TABLE then convert it.
