Taxopress Category problem

I use the Taxopress plugin, which is a great plugin, but I have a problem when I want to categorize the products, for example iPhone 13 Pro Max recognizes it, but unfortunately puts it in the iPhone 13 category as well. I want it to appear only in the iPhone 13 Pro Max category. Is there any solution?
