if the beam is not too long the deflection control not needed like Turkish standart TS500 says if (clear distance / cantilever beam height < 5 ) then u do not need to control the deflection.
i couldn't open your file because it saved on demo version but as i understood your some beams don't have floor because of that ide says these beams are not connected to story rigid diaphragm and if your project doesn't have rigid diaphragm ide offers u to solve the vertical load with a different method which does not need rigid diaphragm
hope this will help u
