Okay lets disect this one
That album is assigned to nothing. It is assigned to members galleries that I see as your assigning an album to an album not to any other category.
Member Galleries - Hair Loss Photos Galleries
He shows 9 photos there
I click his gallery where the albums are displayed and test shows 1 photo
Hairlosspics Gallery - Hair Loss Photos Galleries
Everything shows the proper count to me. I am simply following your breadcrumb trail to see how you have it configured. If you do not assign albums to categories the count is included in the members gallery count which I show it is.
