I'm looking at leads with an empty acquisition program and it seems that some leads had one but that field is empty now. I looked into the lead activity and noticed that there was a "Change Program Status" from "Engaged" to "Not in program" for the specific program that is listed as Registration Source.
I guess that can be the reason the Acquisition Program is now empty since the lead is no longer a member of the program that initially acquired it. Anyone can confirm that?
I can't find what triggered the Change Program Status to Not in program, is it something done automatically by Marketo?
