Record to Record Auto-Creation - Error "Must select an Auto creator if Auto Creation Setup is select

Hello,

I'm updating a workflow to auto-create another BP record. I specifically selected one action on the form that would auto-create a BP record. Under the action properties  I checked the box " Auto-create other record". I added the other BP and chose the option "Header and System Tabs" under Auto-Populate.

I've created a DE that uses Data Definition of BP Creator. I've added it to the source BP upper form I wish to use to populate the fields on the destination form in the destination BP.

I've gone to the Auto-Creation Processes link to set up auto-creation on the upper form.
