It's probably because the items don't register as different items, server-side. +3 Oak Log, Oak Log and +1/+2 Oak Log are all the same item. They would have to go down the list one by one. It's necessary to differentiate +3 and NQ though, I agree. Most of the time, I have no interest in NQ materials at all, so I waste a lot of time checking if they're +3 or not. I just don't know if it's a priority right now for the amount of work that might be involved.
