How to configure Djano-oscar to filter products by attributes?

Question

Django

Understanding django-oscar.
I have products of different classes (ProductClass) in my catalog, for example.
Clothes, with attributes: Size, Gender
Books, with attributes: Author, Genre

ProductCategory is the same as ProductClass, i.e.

there are also two categories - Clothes, Books I select the Clothing category, and in the filter I see:

Sizes:
- S
- M
- L
- XL

Gender:
- male
- female

Now I see ALL values ​​​​of ALL attributes in the filter.
