Hello Marketo Community,
I am having an issue with Marketo updating my Salesforce standard field Lead Source. Occasionally Marketo is changing my lead source to CRM Lead. I do not have this as one of my picklist field options. Has anyone run into this issue and can guide me on how I can stop this from happening. I can't pinpoint what is triggering this update but I can see that Marketo is updating the lead and changing the field.
