I have set up matching for the lead and contact records. The only attribute I am matching is Email.
When a Contact or Lead is found in CRM to have the same email, I do not want a new record created.
This is not working because duplicate contacts and leads are still being created from event registration despite having the same email. On the Marketing form itself I have it set up as well but nothing

I have found two hidden fields that are blank. Should these not populate with the strategy records I have created for a Lead and a Contact?

Can anyone tell me what I am doing wrong?
Again
1. I have create two Form Matching Records. One for Lead one for Contact. Both use Email
2. Under Event Administration I have set it up for Contacts to match on email (not sure why I need both)

3. On a marketing form I select Event Matching to be Email. The two lookups in my screenshot are hidden fields (OOB) and do not populate. Not sure if they should populate.
