You can add a blank value when you are in the "Extract Data" action:

1. Click anywhere (for example, the blank place) on the web page  ➜ Choose "Extract text", and a data field will be generated automatically ➜ Click "Save".

 2. Select the “Customize Field” button ➜ Choose “Define data extracted” ➜ Choose "Use a fixed value" under the "Extract additional values" option (Leave the textbox blank) ➜ Click "OK" ➜ Click "Save".

Then you will see the data field has been added with a blank value. You can rename the data field if you'd like.
