After you have made changes to a model after creating a list you indeed have to update your document. That new document can be accessed by the document manager. To remove lists that did not work you can delete documents just like you delete drawings, again done in the drawing manager. You can also delete them directly in your job folder in the extract s folder.
Next time you need to create a list it will be our pleasure to assist you in doing so. Write us a mail a couple of hours in advance and we will free up some time to walk you thru those steps.
