Certain fields that are in your Facebook Lead Ad forms are not populating on the lead when it is created in Marketo.
1.) Check the Activity Details of the “Fill Out Facebook Lead Ad” activities to see if there are any unmapped form fields included with the standard Lead Ad data fields.
Unmapped form fields will show up with the field name on the left, and value on the right. Note that the other Lead Ad standard fields are not actually on the form. This is because these are default metadata fields created by the integration.
2. )Navigate to Admin > LaunchPoint and update your Facebook Lead Ad service to map that field to a Marketo field, so the data can populate over. Instructions for doing so can be found here: Map Custom Fields to Marketo - Marketo Docs - Product Documentation
