Hi Carlos, thanks for your followup on this. I just wanted to clarify that this isn't a bug, and is working as expected. After editing those fields you need to click the Save button at the top to save the overall form. In our latest version you'll see the Save button is highlighted to indicate this needs to be done. For your second request you can likely open the form then use the Print to PDF functionality in your browser to get a PDF export of those responses.
