We are experiencing an issue where duplicate leads are created for 1 event registration form submission.
1. Someone fills in the event registration form, therefore registering for the event. (Create leads for event registrations is set to yes.)
2. Lead is created with the Topic field populated using a form field hidden on the Event Registration Form.
3. Duplicate lead is created with Topic field populated with the Event Name.
It doesn't happen for every registration and it doesn't happen for every event.
Do we have an incorrect setting somewhere? What could be causing this?
