RAM Connection Gusset Plate design issue

Hi 
I am trying to design a brace column connection with a base plate. I am using the smart gusset plate option to design in RAM connection. The frame was imported from a design that was completed in RAM frame. I am using a W 10x33 for my column and if I set the base plate dimension to 16"x16" the design is being reported as inadequate and it cites section DG1 B.4.1 and it requires the dimension to 15.73"x26.22". I checked the code and it requires the 15.73x13.96 (bf +2*3). Am I missing something here? Is there an actual bug in the code?
