The value is not coming from Marketo - it's coming from the browser itself. The issue is caused by browser autofill. I got exactly the same problem when I autofilled the form in my Chrome browser. Here's how to set up autofill for your Chrome (might be a problem in other browsers too): Fill out forms automatically - Computer - Google Chrome Help
To my knowledge, there's no clear description available as to how to control which value goes where and Chrome is ignoring attempts to turn off the autocomplete function by design, but there are some things you could do:
- Add a hidden field to the form preceding the "Comments" field (it should be invisible to all, and be autopopulated with address only for those who actually autofill it);
- Play around with the "Comments" field type - try changing the type of field for the comments section, for example, make it a string instead (not sure if it will actually help but it might);
- Add a visible address field to the form so the autofill should populate it instead (it will make the form longer for all users though).
None of these solve the problem, but they may be helpful as workarounds. Hope that helps.
