The SmugMug hierarchy is Category>subcategory>gallery>image
There are no sub galleries.
Your images must be in galleries, and galleries must be in categories. You can also add an extra level of sort between categories and galleries, using subcategories. They allow you to subdivide a category like Weddings or Sports into smaller groups, so your viewers can easily find the galleries they want to see.
In your case,
Subcategory:Levi and Ethan
