Has anyone figured this out yet? I am having the same problem. I created a subcategory and then several subcategories under that. My total for the main subcategory is 0, since all the images are in the subcategory under that. For example:
Category: Zoo Special Events (5)
Subcategory: Egg Day (5)
Subcategory: Migratory Bird Day (0)
Sub-Subcategory: Games (15)
Sub-Subcategory: Art Show (20)
This is very confusing, because only the main and subcategory show up in the main categories page, so it looks like there are no images under Migratory Bird Day, when there are actually 35. The user doesn't know to click on it and look for the subcategories since it says there are 0 images.
If this cannot be solved, is there an easy way to show more levels of subcategory on the main category list?
