Cannot Activate Mapping

Hello, 

I see an error (“Cannot Activate Mapping- Can’t Map Salesforce Field to Two Questions: undefined, undefined, undefined”)  when trying to activate a form mapping within Typeform. This error came out of nowhere as the form was working less than 24 hours ago. 

I currently only have two questions mapped in the form “Email” which is mapped via a hidden field on the form and one other question. 

Any idea what this could be? Attaching screenshots.
