Need your help. It seems every time a lead is merged in Marketo and the source is SFDC, the lead is re-added to the SFDC campaigns that the original lead was a member of. So, if John Doe filled out form X and was added to the corresponding SFDC campaign, then he comes through again and is merged by MKTO, then the new merged record is added to the SFDC campaign again.
I have flows that are triggered when a contact is added to a salesforce campaign. This merging behavior is causing these campaigns to trigger erroneously.
