AFM + custom logging profile with some chosen fields for storage format

Hello, I have AFM running on 12.1. I created my own logging profile and I assigned it to a VIP. The same VIP also has firewall policy assigned (for now it is staged). While creating that logging profile I chose some of the fields for storage formats. Despite that from what I can see in the logs all the fields are logged and not the ones I decided to choose. Why? Where did I make my mistake?
