VOR Tracking gave me the right answer.
When creating the aircraft profile in the w&b leave step 3 unchecked and (as it says) it will default to utility. The only thing is I now have two aircraft in my inventory with the same tail number. I don't see a way to differenciate the names in the inventory list. I have to check the listed gross weight as soon as I choose an aircraft.
I have the utilitary profile listed second and right now I'm only flying one plane, so it's not too confusing. If I had multiple planes, I'd do the same for all
