New Leads created via lead gen form do not flow through my trigger campaign

Hi,

I have a problem. We have set up lead gen form in Marketo and the submissions for these forms from LinkedIn to Marketo are working fine. Fields are mapped, all good.

Problem: I have set up a trigger campaign that says:

Person is created

filled out form = lead gen form

fills out form = lead gen form

and then a flow step to change some data values

Issue:

The leads that are created via API lead gen form do not flow through this campaign. I dont understand why? The campaign should check if a person is created and filled out the form then do the flow step but it does not work.

If I create a filter campaign with the same criteria I find all of the newly created leads and can perform the flow. I dont understand why this does not work with a trigger?
