subcategory filtering

Hello,

I would like to ask something about your plugin. I have one category and a lot of subcategories of this.
If i check category in my filters it displays all products of this https://prnt.sc/234l326
. Then, if i check one subcategory, it filters products of categoy and subcategory.

Is it possible to display products only from subcategory selection?

I hope its clear.
Please help,
Thanks in advance
