Why are contacts auto-merged after chatflow submission in HubSpot?

VStar — Thu, 22 Jan 2026 10:35:18 GMT

Hi, I am experiencing an issue where a Chatflow submission triggered an automatic merge (performed by an "Unknown User").

During this merge, the "Message" property was overwritten with an older value from the primary contact, as shown in the attached screenshot.

How is this automatic merge triggered in Chatflows, and is there a way to disable it or change the logic so that the newest data takes precedence? We need the actual, most recent data in our properties, not the legacy values from the primary contact.

Thanks for the tag @BérangèreL (and welcome to the community @VStar !). Sorry but I don't have an answer here. I haven't seen this behavior before, so if it were me I'd be in touch with HubSpot Support to hopefully deduce what happened.
