Value of "Source" changed, with no reason

Today we realised that in a few hundred contacts the value of “Source” field in “Contact properties” changed from various values to a specific one. For no reason.

This is a new one. Have you heard it before?

Possible reasons?

Thank you in advnce

Hi @prozakis

Thank you for reaching out!

If you hover your mouse on the source property and click on Details, you should have more information on where the change is coming from.

Then, you can consult this documentation to get more information on what you found.

Hope that helps.
Have a lovely day,
Tiphaine.

Found the culprit. Zapier automation was changing the source.

Thnaks a lot for your help
