SFDC Lead to Contact Conversion

Hi Nation!


We received a Failed: CANNOT_UPDATE_CONVERTED_LEAD: cannot reference converted lead error recently. The person was a member of a program, synced to a SFDC campaign, and achieved the success criteria. Our inside sales team member converted the SFDC lead to a contact. In a later program, that same person was selected based on a smart list that included members of the previous program. The new program was active when we received the error.


Searching in SFDC, there is only one contact record for this person. In Marketo, there are two records: one with SFDC Type: Lead and one with SFDC Type: Contact. I was under the impression that, when a SFDC lead was converted into a contact, the Marketo person record followed.

Why would we have two records for the same person in Marketo in this instance?
