Confusing Action in Activity Log + Smart Campaign
Hi there,
We have a smart campaign called Lead Source -> Web Direct.
It has triggers "Person is Created" and "Filled out form is any".
Here is the flow:

There are no other flow steps after step 4.
We had a lead go through the workflow.
It completed Step 1 delay
It completed step 2, resolving to "Do Nothing"
It completed Step 3, updating Person Source to Web Direct.
Then... it re-updated its Person Source to "Web"
Then, it synced to SFDC.

If I go into the Activity Details, it looks like sfdc was the source of the change (??):

can you help?
