I'm having problems with the "Customize How Records Get Approved with Approvals" trail.

After following the proper setup, when I go to add in the field updates, the Object defaults to Opportunity, and my choices for type are "Existing customer" variants.

I have added the two options in the accounts-type dropdown, and have followed the trailhead tutorials found on the forums up until this part.

How do I switch the object from Opportunity to Account?
