2016 Toyota Corolla, No air to defrost

When I change to defrost there is brief pause like the air flow is changing direction but then the air just continues to come out of the top vents and not the front window defrost vents. When I look behind the glove box (to the left of the cabin air filter compartment) I can see the gear moving as a go through the air flow settings. I have attached pictures of the gear position when I am in the upper air vent or defrost settings. Can someone confirm that the gear is in the proper position when I am on the defrost setting (and therefore the problem is downstream of the gear)?
