We have a custom field in Pardot that is synced with a field in Salesforce. The setting Keep this field’s type and possible values (for dropdowns, radio buttons, checkboxes) in sync with the CRM is enabled. In Salesforce there is a default value for this field. When a prospect submits a certain form handler, I can see in the Audits section that this field is filled with the default value, even though this field is not present in the form handler (nor in the form on the website). Moreover, the time this field is populated is the same the form handler is submitted and the source is the same - Web Tracking and not CRM, as I would expect if it was filled because of the sync with the CRM. Any clue on why this happens?
