How to display Cherry Picker 3.7 in categories?

Question

Joomla

Hello, I have a Cherry Picker 3.7 module in my online store (Joomla 2.5, Virtuemart 2.6.14), everything works fine. But the problem is that there are 3 levels of categories on the site, and so at the lowest level of categories where products are displayed naturally, the product filter is displayed, but at the second level of categories, products are displayed with a hack and the filter is not displayed there, although in the Cherry Picker module there are checkboxes next to these categories. Tell me how to display the filter in the categories of the 2nd level?
