Moving Bird's Eye view

Hope I can describe this clearly. Just installed a Ring Doorbell Pro. Having trouble with Bird's eye View. Imagine looking down on my house. I can see the porch and house. I know, DUH. when I select my doorbell in the Ring app and select Motion Settings, I can see my porch, house and Bird's eye zone. My problem is the zone covers my roof, but NOT my porch. How do I move the zone to cover my porch?
