Filling out a form changed the lead source, when it shouldn't

[Jenna_Weinerman]

Hi all,

We have contacts and leads that were in our database for months under Lead Source A. They filled out a form to download content and the source changed to Lead Source B. I'm not sure why that changed when source is a field that is supposed to always remain as the original lead source. A source shouldn't change just because they downloaded a piece of content. Any idea what's going on? Also, is there a way to find out if someone was already in the database before filling out the form vs. filling out the form as a new lead?

Thank you so much!
Jenna

Have you blocked updates to the Lead Source field?
