I have encountered an issue when setting up my initial SFDC sync with Marketo.
As you can see below the visibility permission is set to 'hidden' for the "2nd: Email" field.
However, it is showing up in the unmapped fields, in fact, all the fields in the screenshot should not be visible.
How should I work around this issue?
Additionally, we have a very customized SFDC instance and these fields are mapped to the opportunity, not the contact object. How should this be handled with Marketo? Should I make custom Marketo fields on the contact hold them in perpetuity?
