Total, as the engines FF is x by however many engines that aircraft has to give the total on the aircraft tab  

The reason the range on both aircraft is similar is because of how AE itself calculates the max payload range. The max fuel range is the standard range we use along with the max payload range (if we have it, in the case of the A350-900ULR we do not) to determine range. I will see if the data is present for both the -900 and -900ULR's max payload range and see what I can do.
