For context, I’m talking about this page: External Catalog Queries
Under the Query Parameters, there is a Subcategory argument which shows all possible subcategories. However, the “9” subcategory is classified under Hats.
This wouldn’t be an issue, however when you try to actually use this category within the API, it gives you that “Category subselection not supported”.
You can see it for yourself here:

Would like for this to be fixed with the correct argument, since I have tried others (such as 6, which are also undocumented and it combines hats and gears into one, whilst I need only hats)
