Problem detected: I can mark any "Data Extraction Form" as "Done". But, if I did set up string fields for the "Data Extraction Form" and they are null, it is illogical that they could be "Done". At bare minimum, I should write, before setting as done, something like (this information was not found on the article) or "(not applicable for this article).
An extraction that extracted nothing at all can never be a "Done" extraction.
